MemoryRegistryError

Errors returned when a memory range or ID registration is invalid.

Variants

Overlap

A requested owner range overlaps an already reserved range.

Fields

existing_crate: String

Crate that already owns the conflicting range.

existing_start: u8

First ID in the existing range.

existing_end: u8

Last ID in the existing range.

new_crate: String

Crate requesting the new range.

new_start: u8

First ID in the requested range.

new_end: u8

Last ID in the requested range.

InvalidRange

The requested range has start > end.

Fields

start: u8

First ID in the requested range.

end: u8

Last ID in the requested range.

DuplicateId(u8)

The memory ID is already registered.

NoReservedRange

The crate attempted to register an ID before reserving any range.

Fields

crate_name: String

Crate attempting to register the ID.

id: u8

Stable-memory ID being registered.

IdOwnedByOther

The ID falls inside a range reserved by another crate.

Fields

crate_name: String

Crate attempting to register the ID.

id: u8

Stable-memory ID being registered.

owner: String

Crate that owns the range containing id.

owner_start: u8

First ID in the owning range.

owner_end: u8

Last ID in the owning range.

IdOutOfRange

The crate has reserved ranges, but none contain the requested ID.

Fields

crate_name: String

id: u8

Stable-memory ID being registered.

ReservedInternalId

Fields

id: u8

Trait Implementations

impl Debug for MemoryRegistryError

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

Formats the value using the given formatter.

impl Display for MemoryRegistryError

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

Formats the value using the given formatter.

impl Error for MemoryRegistryError

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>)
