Struct Range 

pub struct Range {
    pub start: Pos,
    pub end: Pos,
    pub ctx: SyntaxCtxIndex,
}

Describes a position in a source code (syntax context). It’s useful to generate error messages.

Fields

start: Pos

end: Pos

ctx: SyntaxCtxIndex

Implementations

impl Range

pub fn new(start: Pos, end: Pos, ctx: SyntaxCtxIndex) -> Range

pub fn ghost_range() -> Range

pub fn mix(&self, next: Range) -> Range

Joins two ranges. It keeps the syntax context of the first one.

pub fn set_ctx(&self, ctx: SyntaxCtxIndex) -> Range

Sets the context of the range,

pub fn encode(&self) -> EncodedRange

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Range

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

Formats the value using the given formatter.

impl Hash for Range

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 Range

fn eq(&self, other: &Range) -> 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 Copy for Range

impl Eq for Range

impl StructuralPartialEq for Range
