}

Errors returned by parse.

Variants

TooSmall

File too small to even contain the 108-byte header.

Fields

got: usize

BadMagic

Magic bytes are not 0x09072000.

Fields

got: u32

NonSquareVsid

xdim and ydim disagree (file format requires square maps).

Fields

x: u32

y: u32

Truncated

A read of need bytes at offset at would run past EOF.

Fields

at: usize

need: usize

BadColumn

While walking column idx’s slab chain, the cursor at offset at would have run past the end of the column data region.

Fields

idx: u32

at: usize

FileTooLarge

File total size > u32::MAX. The internal column_offset table uses u32 because realistic maps fit comfortably.

Fields

got: usize

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ParseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ParseError

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.

impl PartialEq for ParseError

fn eq(&self, other: &ParseError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
