Struct TemplateParseError

pub struct TemplateParseError { /* private fields */ }

Implementations

impl TemplateParseError

pub fn with_span(kind: TemplateParseErrorKind, span: Span<'_>) -> Self

pub fn with_source( self, source: impl Into<Box<dyn Error + Send + Sync>>, ) -> Self

pub fn expected_type(expected: &str, actual: &str, span: Span<'_>) -> Self

pub fn expression(message: impl Into<String>, span: Span<'_>) -> Self

Some other expression error.

pub fn extend_keyword_candidates<I>(self, other_keywords: I) -> Self

where I: IntoIterator, I::Item: AsRef<str>,

If this is a NoSuchKeyword error, expands the candidates list with the given other_keywords.

pub fn extend_function_candidates<I>(self, other_functions: I) -> Self

where I: IntoIterator, I::Item: AsRef<str>,

If this is a NoSuchFunction error, expands the candidates list with the given other_functions.

pub fn extend_alias_candidates(self, aliases_map: &TemplateAliasesMap) -> Self

Expands keyword/function candidates with the given aliases.

pub fn kind(&self) -> &TemplateParseErrorKind

pub fn origin(&self) -> Option<&Self>

Original parsing error which typically occurred in an alias expression.

Trait Implementations

impl AliasExpandError for TemplateParseError

fn invalid_arguments(err: InvalidArguments<'_>) -> Self

Unexpected number of arguments, or invalid combination of arguments.

fn recursive_expansion(id: AliasId<'_>, span: Span<'_>) -> Self

Recursion detected during alias substitution.

fn within_alias_expansion(self, id: AliasId<'_>, span: Span<'_>) -> Self

Attaches alias trace to the current error.

impl Debug for TemplateParseError

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

Formats the value using the given formatter.

impl Display for TemplateParseError

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

Formats the value using the given formatter.

impl Error for TemplateParseError

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.
