Struct liquid_core::error::Error

pub struct Error { /* private fields */ }

Compiler error

Implementations

impl Error

pub fn with_msg<S: Into<KString>>(msg: S) -> Self

Create a new compiler error with the given message

pub fn trace<T>(self, trace: T) -> Selfwhere T: Into<KString>,

Add a new call to the user-visible backtrace

pub fn context<K, V>(self, key: K, value: V) -> Selfwhere K: Into<KString>, V: Into<KString>,

Add context to the last traced call.

Example context: Value that parameters from the trace evaluate to.

pub fn cause<E: ErrorClone>(self, cause: E) -> Self

Add an external cause to the error for debugging purposes.

pub fn into_err<T, E>(self) -> Result<T, E>where Self: Into<E>,

Simplify returning early with an error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.
