Struct csv::Error

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

An error that can occur when processing CSV data.

This error can happen when writing or reading CSV data.

There are some important scenarios where an error is impossible to occur. For example, if a CSV reader is used on an in-memory buffer with the flexible option enabled and one is reading records as raw byte strings, then no error can occur.

Implementations§

source§

impl Error

source

pub fn kind(&self) -> &ErrorKind

Return the specific type of this error.

source

pub fn into_kind(self) -> ErrorKind

Unwrap this error into its underlying type.

source

pub fn is_io_error(&self) -> bool

Returns true if this is an I/O error.

If this is true, the underlying ErrorKind is guaranteed to be ErrorKind::Io.

source

pub fn position(&self) -> Option<&Position>

Return the position for this error, if one exists.

This is a convenience function that permits callers to easily access the position on an error without doing case analysis on ErrorKind.
