Struct lib_ruby_parser::Loc

#[repr(C)]
pub struct Loc {
    pub begin: usize,
    pub end: usize,
}

Representation of any location in the given input

Fields

begin: usize

Begin of the Loc range

end: usize

End of the Loc range

Implementations

impl Loc

pub fn to_range(&self) -> Range<usize>

Converts location to a range

pub fn size(&self) -> usize

Returns size of the Loc (i.e. end - begin)

pub fn with_begin(&self, begin: usize) -> Loc

Returns a new Loc with given begin and current end

pub fn with_end(&self, end: usize) -> Loc

Returns a new Loc with given end and current begin

pub fn adjust_begin(&self, delta: i32) -> Loc

Adds given delta to begin

pub fn adjust_end(&self, d: i32) -> Loc

Adds given delta to end

pub fn resize(&self, new_size: usize) -> Loc

Returns a new Loc with the same begin, but adjusted end, so that its size is equal to given new_size

pub fn join(&self, other: &Self) -> Loc

Joins two Locs by choosing min(begin) + max(end)

pub fn is_empty(&self) -> bool

Returns true if Loc is empty (i.e. begin == end)

pub fn source(&self, input: &DecodedInput) -> Option<String>

Returns source code of the current Loc on a given Input

Trait Implementations

impl Clone for Loc

fn clone(&self) -> Loc

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Loc

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

Formats the value using the given formatter.

impl Default for Loc

fn default() -> Loc

Returns the “default value” for a type.

impl PartialEq<Loc> for Loc

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

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

const 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.
