Trait Alloc 

pub trait Alloc {
    // Required method
    fn alloc(&self, layout: Layout) -> Result<NonNull<u8>, AllocError>;

    // Provided method
    fn zalloc(&self, layout: Layout) -> Result<NonNull<u8>, AllocError> { ... }
}

A memory allocation interface.

Required Methods

fn alloc(&self, layout: Layout) -> Result<NonNull<u8>, AllocError>

Attempts to allocate a block of memory fitting the given Layout.

Errors

• AllocError::AllocFailed if allocation fails.
• AllocError::ZeroSizedLayout if layout has a size of zero.

Provided Methods

fn zalloc(&self, layout: Layout) -> Result<NonNull<u8>, AllocError>

Attempts to allocate a zeroed block of memory fitting the given Layout.

Errors

• AllocError::AllocFailed if allocation fails.
• AllocError::ZeroSizedLayout if layout has a size of zero.
