Struct iroh_bytes::store::mem::MutableMemFile

pub struct MutableMemFile(/* private fields */);

A mutable file like object that can be used for partial entries.

Implementations

impl MutableMemFile

pub fn with_capacity(capacity: usize) -> Self

Create a new empty file

pub fn freeze(self) -> Bytes

Freeze the data, returning the content

Note that this will clear other references to the data.
