Struct serde_cbor::Error

source ·
pub struct Error(/* private fields */);
Expand description

This type represents all possible errors that can occur when serializing or deserializing CBOR data.

Implementations§

source§

impl Error

source

pub fn offset(&self) -> u64

The byte offset at which the error occurred.

source

pub fn classify(&self) -> Category

Categorizes the cause of this error.

source

pub fn is_io(&self) -> bool

Returns true if this error was caused by a failure to read or write bytes on an IO stream.

source

pub fn is_syntax(&self) -> bool

Returns true if this error was caused by input that was not syntactically valid CBOR.

source

pub fn is_data(&self) -> bool

Returns true if this error was caused by data that was semantically incorrect.

source

pub fn is_eof(&self) -> bool

Returns true if this error was caused by prematurely reaching the end of the input data.

source

pub fn is_scratch_too_small(&self) -> bool

Returns true if this error was caused by the scratch buffer being too small.

Note this being true implies that is_io() is also true.
