Enum EffectLoggerError 

pub enum EffectLoggerError {
    Sink(String),
}

Errors that a log sink may produce.

Currently the only backend is tracing, which is infallible, so no variant is ever constructed at runtime. The type exists so that callers can compose it into their E bound and gain compile-time proof that the logger’s error channel is handled, without changing the API when a fallible backend (e.g. a network sink) is added later.

Variants

Sink(String)

The underlying log sink returned an error.

Trait Implementations

impl Clone for EffectLoggerError

fn clone(&self) -> EffectLoggerError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EffectLoggerError

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

Formats the value using the given formatter.

impl Display for EffectLoggerError

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

Formats the value using the given formatter.

impl Error for EffectLoggerError

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<Infallible> for EffectLoggerError

fn from(e: Infallible) -> Self

Converts to this type from the input type.

impl Hash for EffectLoggerError

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a, R> IntoBind<'a, R, EffectLogger, EffectLoggerError> for EffectLogger

where R: Get<EffectLogKey, Here, Target = EffectLogger> + 'a,

Implementing IntoBind for EffectLogger makes ~EffectLogger valid inside any effect! whose environment R holds an EffectLogger under EffectLogKey. The zero-sized struct acts as its own “request token”: passing it to ~ copies the concrete value out of R and binds it as a local variable.

fn into_bind( self, r: &'a mut R, ) -> BoxFuture<'a, Result<EffectLogger, EffectLoggerError>>

Turns self into a boxed future given the environment r.

impl PartialEq for EffectLoggerError

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.
