Enum MappingSessionRequest 

pub enum MappingSessionRequest {
    Open {
        key: u64,
        identifier: Vec<u8>,
        responder: MappingSessionOpenResponder,
    },
    Close {
        key: u64,
        responder: MappingSessionCloseResponder,
    },
    #[non_exhaustive]
    _UnknownMethod {
        ordinal: u64,
        control_handle: MappingSessionControlHandle,
        method_type: MethodType,
    },
}

Variants

Open

Registers a node’s extents in the mapping session, returning its uncompressed size in bytes.

The filesystem resolves the identifier to locate the node on disk and transmits its extent mappings to the block driver associated with key.

Fields

key: u64

identifier: Vec<u8>

responder: MappingSessionOpenResponder

Close

Unregisters a node’s extents from the session by its session-unique key.

Fields

key: u64

responder: MappingSessionCloseResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: MappingSessionControlHandle

method_type: MethodType
