Core.Builtins

Builtin Function APIs

The following Builtin function APIs are considered unstable, but provide the basic definitions for what defines the abilities and behaviors of a Julia program. They are typically accessed through a higher level generic API.

# Core.memoryrefnew — Function.

Core.memoryrefnew(::GenericMemory)
Core.memoryrefnew(::GenericMemoryRef, index::Int, [boundscheck::Bool])

Return a GenericMemoryRef for a GenericMemory. See memoryref.

Julia 1.11

This function requires Julia 1.11 or later.

source

# Core.memoryrefoffset — Function.

Core..memoryrefoffset(::GenericMemoryRef)

Return the offset index that was used to construct the MemoryRef. See memoryref.

Julia 1.11

This function requires Julia 1.11 or later.

source

# Core.memoryrefget — Function.

Core.memoryrefget(::GenericMemoryRef, ordering::Symbol, boundscheck::Bool)

Return the value stored at the MemoryRef, throwing a BoundsError if the Memory is empty. See ref[]. The memory ordering specified must be compatible with the isatomic parameter.

Julia 1.11

This function requires Julia 1.11 or later.

source

# Core.memoryrefset! — Function.

Core.memoryrefset!(::GenericMemoryRef, value, ordering::Symbol, boundscheck::Bool)

source

# Core.memoryref_isassigned — Function.

Core.memoryref_isassigned(::GenericMemoryRef, ordering::Symbol, boundscheck::Bool)

Return whether there is a value stored at the MemoryRef, returning false if the Memory is empty. See isassigned(::Base.RefValue), Core.memoryrefget. The memory ordering specified must be compatible with the isatomic parameter.

Julia 1.11

This function requires Julia 1.11 or later.

source

# Core.memoryrefswap! — Function.

Core.memoryrefswap!(::GenericMemoryRef, value, ordering::Symbol, boundscheck::Bool)
