Struct rustemo::Location

pub struct Location {
    pub start: Position,
    pub end: Option<Position>,
}

Describes a span from start till end in the parsed input.

Start is mandatory while the end is not.

The location doesn’t keep the path of the parsed file on purpose as it will be the same for the single parse tree so it would either unnccessary waste memory, in case of owned strings, or propagate lifetime information throught the API in case of borrowed string slice.

The path is kept on the parsing context and there is the method on the context to produce the display of the location with the full file path.

Fields

start: Position

The start position of the range.

end: Option<Position>

The end position. Sometimes it is not known or relevant.

Implementations

impl Location

pub fn new(start: Position, end: Position) -> Self

pub fn from_start(start: Position) -> Self

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Location

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

Formats the value using the given formatter.

impl Default for Location

fn default() -> Location

Returns the “default value” for a type.

impl PartialEq for Location

fn eq(&self, other: &Location) -> 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.
