Struct rsass::input::SourcePos

pub struct SourcePos { /* private fields */ }

A specific part of input.

This is represented as start and end offsets into SourceFile. The sourcefile is internally reference counted, so a SourcePos can be cheaply cloned, but does not implement copy.

Implementations

impl SourcePos

pub fn fragment(&self) -> &[u8]

This span of input as actual bytes.

pub fn is_at_end(&self) -> bool

Return true if the pos is at the end of the source.

pub fn line_no(&self) -> usize

Return the line number for (the beginning of) this span.

pub fn show(&self, out: &mut impl Write) -> Result

Show this source position.

Dislays the line containg the position, highlighting the position. This is typically used when there is one source position relevant for an error.

pub fn show_two( out: &mut Formatter<'_>, one: &Self, one_name: &str, other: &Self, other_name: &str ) -> Result

Show two source positions together.

pub fn is_builtin(&self) -> bool

True if the source of this position is built-in.

pub fn file_url(&self) -> &str

Get the resolved name / url of the file this source is loaded from.

Trait Implementations

impl Clone for SourcePos

fn clone(&self) -> SourcePos

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourcePos

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

Formats the value using the given formatter.

impl From<SourceFile> for SourcePos

fn from(source: SourceFile) -> Self

Converts to this type from the input type.

impl Ord for SourcePos

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for SourcePos

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for SourcePos

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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