Module ptr

Macros

• addr_of
  Creates a const raw pointer to a place, without creating an intermediate reference.
• addr_of_mut
  Creates a mut raw pointer to a place, without creating an intermediate reference.

Structs

• NonNull
  *mut T but non-zero and covariant.
• AlignmentExperimental
  A type storing a usize which is a power of two, and thus represents a possible alignment in the Rust abstract machine.
• DynMetadataExperimental
  The metadata for a Dyn = dyn SomeTrait trait object type.

Traits

• PointeeExperimental
  Provides the pointer metadata type of any pointed-to type.

Functions

• addr_eq
  Compares the addresses of the two pointers for equality, ignoring any metadata in fat pointers.
• copy^⚠
  Copies count * size_of::<T>() bytes from src to dst. The source and destination may overlap.
• copy_nonoverlapping^⚠
  Copies count * size_of::<T>() bytes from src to dst. The source and destination must not overlap.
• dangling
  Creates a new pointer that is dangling, but non-null and well-aligned.
• dangling_mut
  Creates a new pointer that is dangling, but non-null and well-aligned.
• drop_in_place^⚠
  Executes the destructor (if any) of the pointed-to value.
• eq
  Compares raw pointers for equality.
• from_mut
  Converts a mutable reference to a raw pointer.
• from_ref
  Converts a reference to a raw pointer.
• hash
  Hash a raw pointer.
• null
  Creates a null raw pointer.
• null_mut
  Creates a null mutable raw pointer.
• read^⚠
  Reads the value from src without moving it. This leaves the memory in src unchanged.
• read_unaligned^⚠
  Reads the value from src without moving it. This leaves the memory in src unchanged.
• read_volatile^⚠
  Performs a volatile read of the value from src without moving it. This leaves the memory in src unchanged.
• replace^⚠
  Moves src into the pointed dst, returning the previous dst value.
• slice_from_raw_parts
  Forms a raw slice from a pointer and a length.
• slice_from_raw_parts_mut
  Forms a raw mutable slice from a pointer and a length.
• swap^⚠
  Swaps the values at two mutable locations of the same type, without deinitializing either.
• swap_nonoverlapping^⚠
  Swaps count * size_of::<T>() bytes between the two regions of memory beginning at x and y. The two regions must not overlap.
• with_exposed_provenance
  Converts an address back to a pointer, picking up some previously ‘exposed’ provenance.
• with_exposed_provenance_mut
  Converts an address back to a mutable pointer, picking up some previously ‘exposed’ provenance.
• without_provenance
  Creates a pointer with the given address and no provenance.
• without_provenance_mut
  Creates a pointer with the given address and no provenance.
• write^⚠
  Overwrites a memory location with the given value without reading or dropping the old value.
• write_bytes^⚠
  Sets count * size_of::<T>() bytes of memory starting at dst to val.
• write_unaligned^⚠
  Overwrites a memory location with the given value without reading or dropping the old value.
• write_volatile^⚠
  Performs a volatile write of a memory location with the given value without reading or dropping the old value.
• fn_addr_eqExperimental
  Compares the addresses of the two function pointers for equality.
• from_raw_partsExperimental
  Forms a (possibly-wide) raw pointer from a data pointer and metadata.
• from_raw_parts_mutExperimental
  Performs the same functionality as from_raw_parts, except that a raw *mut pointer is returned, as opposed to a raw *const pointer.
• metadataExperimental
  Extracts the metadata component of a pointer.
