Enum Error 

pub enum Error {
    Read {
        pos: usize,
        len: usize,
        size: usize,
    },
    Seek {
        pos: usize,
        size: usize,
    },
    Other {
        pos: usize,
        source: Box<dyn Error + Send + Sync>,
    },
}

An error occurred when reading.

Variants

Read

Attempted to read mode data than is available.

Fields

pos: usize

len: usize

size: usize

Seek

Attempted to seek to an out-of-bounds position.

Fields

pos: usize

size: usize

Other

Some other error happened.

This is normally used by check, but can be used to embed any error you want.

Fields

pos: usize

source: Box<dyn Error + Send + Sync>

Implementations

impl Error

pub fn pos(&self) -> usize

The position the error happened at.

pub fn pos_mut(&mut self) -> &mut usize

The position the error happened at, but mutably.

This can be useful for mapping errors in subslices.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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.
