Enum DataDescError 

pub enum DataDescError {
    SizeNotPageMultiple(u64),
    BadLen(u32),
    OutOfRange(u32),
    PageIndexOutOfRange {
        page_index: u32,
        page_count: u64,
    },
    NotCanonical(u32),
}

Structural faults in a DataDesc relative to the Image arena, surfaced eagerly at deblob (per the strict-interface rule: fail loud).

Variants

SizeNotPageMultiple(u64)

size is not a PAGE_SIZE multiple.

BadLen(u32)

A page-ref len is 0 or exceeds PAGE_SIZE.

OutOfRange(u32)

A page-ref window [arena_off, arena_off + len) exceeds the arena.

PageIndexOutOfRange

A page_index is >= size / PAGE_SIZE.

Fields

page_index: u32

page_count: u64

NotCanonical(u32)

Pages are not strictly ascending by page_index (unsorted or duplicate).

Trait Implementations

impl Clone for DataDescError

fn clone(&self) -> DataDescError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataDescError

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

Formats the value using the given formatter.

impl PartialEq for DataDescError

fn eq(&self, other: &DataDescError) -> 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.
