Struct TargetRefusal 

pub struct TargetRefusal { /* private fields */ }

Why an encoder could not resolve or deliver a write target.

The refusal carries the encoder catalog once, beside the request-state reason, so every reason is rendered and reported against the same catalog.

Implementations

impl TargetRefusal

pub fn new(kind: TargetRefusalKind, available: TargetCatalog) -> Self

Associates one request-state reason with the refusing encoder catalog.

pub fn unknown_explicit( requested: impl Into<String>, available: TargetCatalog, ) -> Self

Builds the refusal for an explicit token outside an encoder catalog.

pub fn format(&self) -> &str

Returns the refusing encoder format.

pub const fn available(&self) -> &'static [TargetDescriptor]

Returns the encoder’s structured synthesis catalog.

Trait Implementations

impl Clone for TargetRefusal

impl Eq for TargetRefusal

impl Error for TargetRefusal

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
