Parsing errors produced when validating a template.

Variants

UnmatchedClosingBrace

Encountered a stray closing brace.

Fields

index: usize

Byte index of the stray } in the original template.

UnterminatedPlaceholder

Placeholder without a matching closing brace.

Fields

start: usize

Byte index where the unterminated placeholder starts.

NestedPlaceholder

Encountered {{ or }} imbalance inside a placeholder.

Fields

index: usize

Byte index of the unexpected brace.

EmptyPlaceholder

Placeholder without an identifier.

Fields

start: usize

Byte index where the empty placeholder starts.

InvalidIdentifier

Identifier is malformed (contains illegal characters).

Fields

span: Range<usize>

Span (byte indices) covering the invalid identifier.

InvalidIndex

Positional identifier is not a valid unsigned integer.

Fields

span: Range<usize>

Span (byte indices) covering the invalid positional identifier.

InvalidFormatter

Unsupported formatting specifier.

Fields

span: Range<usize>

Span (byte indices) covering the unsupported formatter.

Trait Implementations

impl Clone for TemplateError

fn clone(&self) -> TemplateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemplateError

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

Formats the value using the given formatter.

impl Display for TemplateError

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

Formats the value using the given formatter.

impl Error for TemplateError

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 PartialEq for TemplateError

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