Struct RawSpan 

pub struct RawSpan {
    pub src_id: FileId,
    pub start: ByteIndex,
    pub end: ByteIndex,
}

A position span identified by a starting byte offset and an ending byte offset in a file.

end is the offset of the last character plus one.

Fields

src_id: FileId

start: ByteIndex

end: ByteIndex

Implementations

impl RawSpan

pub fn fuse(self, other: RawSpan) -> Option<RawSpan>

Fuse two spans if they are from the same source file. The resulting span is the smallest span that contain both self and other.

pub fn from_codespan(src_id: FileId, span: Span) -> Self

Create a RawSpan from a span as represented by the codespan library.

pub fn from_range<T>(src_id: FileId, range: Range<T>) -> Self

where u32: TryFrom<T>,

Create a span from a numeric range. If either start or end is too large to be represented, u32::MAX is used instead.

pub fn to_range<T>(self) -> Range<T>

where T: TryFrom<u32> + Max,

Convert this span to a numeric index range. If either start or end is too large to be represented, T::MAX is used instead.

pub fn start_pos(&self) -> RawPos

Return the start of this range.

pub fn contains(&self, pos: RawPos) -> bool

Check whether this span contains a position.

pub fn contains_span(&self, other: RawSpan) -> bool

Check whether this span contains another span.

Trait Implementations

impl Clone for RawSpan

fn clone(&self) -> RawSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RawSpan

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

Formats the value using the given formatter.

impl From<RawSpan> for Span

fn from(span: RawSpan) -> Self

Converts to this type from the input type.

impl From<RawSpan> for TermPos

fn from(span: RawSpan) -> Self

Converts to this type from the input type.

impl Hash for RawSpan

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 RawSpan

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

An inclusion ordering for spans: s1 is smaller than s2 if they are located in the same file and s1 is included in s2 when seen as position intervals.

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

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.
