pub struct Error { /* private fields */ }
Expand description
Decoding error.
Implementations
sourceimpl Error
impl Error
sourcepub fn end_of_input() -> Self
pub fn end_of_input() -> Self
The end of the input bytes has been reached.
sourcepub fn type_mismatch(ty: Type) -> Self
pub fn type_mismatch(ty: Type) -> Self
A type error.
sourcepub fn message<T: Display>(msg: T) -> Self
pub fn message<T: Display>(msg: T) -> Self
Construct an error with a generic message.
With feature "alloc"
any type T: Display
is accepted which allows
formatted strings. Otherwise only a &'static str
can be used as a
message.
sourcepub fn custom<T: Error + Send + Sync + 'static>(err: T) -> Self
pub fn custom<T: Error + Send + Sync + 'static>(err: T) -> Self
A custom error.
Requires feature "std"
.
sourcepub fn with_message<T: Display>(self, msg: T) -> Self
pub fn with_message<T: Display>(self, msg: T) -> Self
Add a message to this error value.
With feature "alloc"
any type T: Display
is accepted which allows
formatted strings. Otherwise only a &'static str
can be used as a
message.
pub fn is_end_of_input(&self) -> bool
pub fn is_type_mismatch(&self) -> bool
pub fn is_message(&self) -> bool
pub fn is_custom(&self) -> bool
