Struct DiagnosticSpan 

pub struct DiagnosticSpan { /* private fields */ }

A generic source span with optional source identity.

Implementations

impl DiagnosticSpan

pub fn new( source: Option<DiagnosticSourceId>, start: DiagnosticPosition, end: DiagnosticPosition, ) -> Result<Self, DiagnosticSpanError>

Creates a diagnostic span and validates that the end is not before the start.

Errors

Returns DiagnosticSpanError::Reversed when end is before start.

pub fn with_source( source: DiagnosticSourceId, start: DiagnosticPosition, end: DiagnosticPosition, ) -> Result<Self, DiagnosticSpanError>

Creates a span with a source identifier.

Errors

Returns DiagnosticSpanError::Reversed when end is before start.

pub fn without_source( start: DiagnosticPosition, end: DiagnosticPosition, ) -> Result<Self, DiagnosticSpanError>

Creates a span without a source identifier.

Errors

Returns DiagnosticSpanError::Reversed when end is before start.

pub const fn source(&self) -> Option<&DiagnosticSourceId>

Returns the optional source identifier.

pub const fn start(&self) -> DiagnosticPosition

Returns the start position.

pub const fn end(&self) -> DiagnosticPosition

Returns the end position.

Trait Implementations

impl Clone for DiagnosticSpan

fn clone(&self) -> DiagnosticSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiagnosticSpan

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

Formats the value using the given formatter.

impl Hash for DiagnosticSpan

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 PartialEq for DiagnosticSpan

fn eq(&self, other: &DiagnosticSpan) -> 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.
