Enum BytesAccessError 

pub enum BytesAccessError {
    UnknownStorage(StorageId),
    InvalidRange {
        offset: u64,
        size: u64,
        allocation_size: usize,
    },
    BorrowConflict {
        requested: Range<usize>,
        existing: Range<usize>,
    },
}

Invalid storage lookup or conflicting safe access.

Variants

UnknownStorage(StorageId)

The ID was never allocated or has already been removed from the storage.

InvalidRange

Offset/size overflow or a range outside the allocation.

Fields

offset: u64

Requested byte offset.

size: u64

Requested byte length.

allocation_size: usize

Actual allocation length.

BorrowConflict

Overlapping ranges may have multiple readers, but no overlapping writer.

Fields

requested: Range<usize>

Requested byte range.

existing: Range<usize>

Conflicting live borrow.

Trait Implementations

impl Eq for BytesAccessError

impl Error for BytesAccessError

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 BytesAccessError

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

Equality operator ==.

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

Inequality operator !=.
