Struct PgIdentifier 

pub struct PgIdentifier { /* private fields */ }

A validated PostgreSQL identifier segment.

Implementations

impl PgIdentifier

pub fn new(input: impl AsRef<str>) -> Result<Self, PgIdentifierError>

Creates an identifier from either unquoted text or a double-quoted identifier token.

Errors

Returns PgIdentifierError when the value is empty, malformed, or not valid for its style.

pub fn unquoted(input: impl AsRef<str>) -> Result<Self, PgIdentifierError>

Creates an unquoted identifier segment using PostgreSQL-style conservative validation.

Unquoted identifiers are stored in lowercase because PostgreSQL folds unquoted names.

Errors

Returns PgIdentifierError when the value cannot be rendered safely without quotes.

pub fn quoted(input: impl AsRef<str>) -> Result<Self, PgIdentifierError>

Creates a quoted identifier segment from raw identifier text.

Errors

Returns PgIdentifierError when the value is empty or contains a control character.

pub fn from_quoted_token(input: &str) -> Result<Self, PgIdentifierError>

Parses a double-quoted SQL identifier token, including doubled embedded quotes.

Errors

Returns PgIdentifierError when the token is not a complete quoted identifier.

pub fn as_str(&self) -> &str

Returns the raw identifier text without SQL quotes.

pub const fn style(&self) -> PgIdentifierStyle

Returns the rendering style.

pub const fn is_quoted(&self) -> bool

Returns true when this identifier renders with double quotes.

pub fn into_string(self) -> String

Consumes the identifier and returns its raw text.

Trait Implementations

impl AsRef<str> for PgIdentifier

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PgIdentifier

fn clone(&self) -> PgIdentifier

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PgIdentifier

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PgIdentifier

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for PgIdentifier

type Err = PgIdentifierError

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for PgIdentifier

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PgIdentifier

fn cmp(&self, other: &PgIdentifier) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PgIdentifier

fn eq(&self, other: &PgIdentifier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PgIdentifier

fn partial_cmp(&self, other: &PgIdentifier) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<&str> for PgIdentifier

type Error = PgIdentifierError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for PgIdentifier
