Struct ProjectionParameter 

pub struct ProjectionParameter { /* private fields */ }

Implementations

impl ProjectionParameter

pub fn new( key: impl AsRef<str>, value: impl AsRef<str>, ) -> Result<Self, ProjectionParameterError>

Creates a projection parameter from non-empty key and value text.

Errors

Returns ProjectionParameterError::EmptyKey when the trimmed key is empty. Returns ProjectionParameterError::EmptyValue when the trimmed value is empty.

pub fn key(&self) -> &str

pub fn value(&self) -> &str

Trait Implementations

impl Clone for ProjectionParameter

fn clone(&self) -> ProjectionParameter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectionParameter

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

Formats the value using the given formatter.

impl Display for ProjectionParameter

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

Formats the value using the given formatter.

impl Hash for ProjectionParameter

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 ProjectionParameter

fn cmp(&self, other: &ProjectionParameter) -> 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 ProjectionParameter

fn eq(&self, other: &ProjectionParameter) -> 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 ProjectionParameter

fn partial_cmp(&self, other: &ProjectionParameter) -> 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.
