Struct SourceLocation 

pub struct SourceLocation {
    pub source: String,
    pub line: Option<u32>,
    pub column: Option<u32>,
}

Location where a configuration value originated.

Fields

source: String

Name of the source (e.g., “config.toml”, “env:APP_HOST”)

line: Option<u32>

Line number in the source (1-indexed), if applicable

column: Option<u32>

Column number in the source (1-indexed), if applicable

Implementations

impl SourceLocation

pub fn new(source: impl Into<String>) -> Self

Create a new source location with just a source name.

pub fn with_line(self, line: u32) -> Self

Add a line number to this location.

pub fn with_column(self, column: u32) -> Self

Add a column number to this location.

pub fn env(var_name: &str) -> Self

Create a location for an environment variable.

pub fn file(path: &str, line: Option<u32>, column: Option<u32>) -> Self

Create a location for a file with optional position.

Trait Implementations

impl Clone for SourceLocation

fn clone(&self) -> SourceLocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceLocation

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

Formats the value using the given formatter.

impl Display for SourceLocation

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

Formats the value using the given formatter.

impl PartialEq for SourceLocation

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