Implementations

impl<T> Loc<T>

pub fn new(inner: T, span: Span, file_id: usize) -> Self

pub fn nowhere(inner: T) -> Self

pub fn strip(self) -> T

pub fn is_same_loc<R>(&self, other: &Loc<R>) -> bool

pub fn map<Y>(self, op: impl FnMut(T) -> Y) -> Loc<Y>

pub fn try_map<Y, E>( self, op: impl FnMut(T) -> Result<Y, E>, ) -> Result<Loc<Y>, E>

pub fn loc(&self) -> Loc<()>

pub fn contains_start<R>(&self, other: &Loc<R>) -> bool

pub fn start_span(&self) -> Loc<()>

pub fn end_span(&self) -> Loc<()>

pub fn shrink_left(&self, s: &str) -> Loc<()>

Shrinks a Loc on the left size by the width of the specified string. For example (( abc )) ^^^^^^^^^ .shrink_left(“((”) results in For example (( abc )) ^^^^^^^

Note that this is only valid if the loc actually points to the specified string, otherwise the behaviour is undefined

If the span is empty, does nothing
