Struct Location 

pub struct Location {
    pub source_name: String,
    pub resource: String,
    pub line: Option<NonZeroU32>,
    pub column: Option<NonZeroU32>,
    pub length: Option<NonZeroU32>,
}

Source and optional position of a configuration value.

Positions are 1-based and stored as NonZeroU32 so that the whole Location (and therefore crate::Error) stays small enough to return by value without triggering clippy::result_large_err. Construct via Location::at, which accepts ordinary usize positions and discards any out-of-range or zero value as “absent”.

Fields

source_name: String

resource: String

line: Option<NonZeroU32>

column: Option<NonZeroU32>

length: Option<NonZeroU32>

UTF-8 character span length for error underlines; defaults to one caret.

Implementations

impl Location

pub fn at( source_name: &str, resource: &str, line: Option<usize>, column: Option<usize>, length: Option<usize>, ) -> Self

pub fn with_length(self, length: usize) -> Self

Trait Implementations

impl Clone for Location

fn clone(&self) -> Location

Returns a duplicate 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 Display for Location

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

Formats the value using the given formatter.

impl PartialEq for Location

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