}

Errors generated during rendering.

Variants

PartialNotFound(String)

Error when a partial could not be found.

VariableNotFound(String, String)

Error when a variable could not be resolved.

HelperNotFound(String)

Error when a helper could not be found.

EvaluatePath(String)

Error when evaluating a path and a syntax error occurs.

Paths can be dynamically evaluated when the evaluate() function is called inside a helper.

PartialCycle(String)

Error when a cycle is detected whilst handling a partial.

HelperCycle(String)

Error when a cycle is detected whilst handling a helper.

PartialIdentifier(String)

Error when a partial is not a simple identifier.

BlockIdentifier(String)

Error when a block is not a simple identifier.

BlockTargetSubExpr

Error attempting to invoke a sub-expression outside of a partial target context.

Helper(HelperError)

Wrap a helper error.

Io(IoError)

Wrap a syntax error. Proxy for IO errors.

Json(Error)

Proxy for JSON errors.

Trait Implementations

impl Debug for RenderError

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

Formats the value using the given formatter.

impl Display for RenderError

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

Formats the value using the given formatter.

impl Error for RenderError

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<Error> for RenderError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for RenderError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<HelperError> for RenderError

fn from(source: HelperError) -> Self

Converts to this type from the input type.

impl From<IoError> for RenderError

fn from(source: IoError) -> Self

Converts to this type from the input type.

impl From<RenderError> for Error

fn from(source: RenderError) -> Self

Converts to this type from the input type.

impl PartialEq for RenderError

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