Struct InterpolationError 

pub struct InterpolationError {
    pub key: String,
    pub line: usize,
    pub source: Option<PathBuf>,
    pub kind: InterpolationErrorKind,
}

Interpolation failures for ${VAR} style expansions.

Fields

key: String

The key whose value was being expanded.

line: usize

The 1-based line where the key was defined.

source: Option<PathBuf>

The source file when known.

kind: InterpolationErrorKind

The specific interpolation failure.

Trait Implementations

impl Clone for InterpolationError

fn clone(&self) -> InterpolationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InterpolationError

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

Formats the value using the given formatter.

impl Display for InterpolationError

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

Formats the value using the given formatter.

impl Eq for InterpolationError

impl Error for InterpolationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<InterpolationError> for Error

fn from(err: InterpolationError) -> Self

Converts to this type from the input type.

impl PartialEq for InterpolationError

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