Struct DynPmm 

pub struct DynPmm<'a, const RAM: bool> { /* private fields */ }

Available on crate feature full only.

A type erased reference to a Pmm.

This is equivalent to &dyn Pmm with the addition that a DynPmm<true> can be converted directly to a DynPmm<false> by calling from or into.

Implementations

impl<'a, const RAM: bool> DynPmm<'a, RAM>

pub const fn into(self) -> DynPmm<'a, false>

Converts to a DynPmm<false>.

pub fn allocate_one(&self) -> Result<Frames<RAM>, AllocError>

where Self: 'static,

Allocates a single owned frame.

Errors

Returns an AllocError if the memory could not be allocated.

pub fn allocate(&self, count: NonZero<usize>) -> Result<Frames<RAM>, AllocError>

where Self: 'static,

Allocates counts number of contiguous owned Frames.

Errors

Returns an AllocError if the memory could not be allocated. This does not mean there is no free memory, just that is there no region of contiguous memory large enough.

pub fn allocate_at( &self, at: RawFrame, count: NonZero<usize>, ) -> Result<Frames<RAM>, AllocError>

where Self: 'static,

Allocates count number of contiguous owned Frames with the first frame being at at.

Errors

Returns an AllocError if the memory could not be allocated. This does not mean there is no free memory, just that is there no region of contiguous memory large enough starting at at.
