Macros

derive 🔒

Defines a derive function named $outer which parses its input TokenStream as a DeriveInput and then invokes the $inner function.

Structs

ImplBlockBuilder 🔒

Enums

FieldBounds 🔒

PaddingCheck 🔒

This enum describes what kind of padding check needs to be generated for the associated impl.

SelfBounds 🔒

Trait 🔒

TraitBound 🔒

BoolExt 🔒

IntoTokenStream 🔒

Functions

derive_eq_inner 🔒

derive_from_bytes_enum 🔒

An enum is FromBytes if:

derive_from_bytes_inner 🔒

derive_from_bytes_struct 🔒

A struct is FromBytes if:

derive_from_bytes_union 🔒

Unions are FromBytes if

derive_from_zeros_enum 🔒

An enum is FromZeros if:

derive_from_zeros_inner 🔒

derive_from_zeros_struct 🔒

A struct is FromZeros if:

derive_from_zeros_union 🔒

Unions are FromZeros if

derive_hash_inner 🔒

derive_into_bytes_enum 🔒

If the type is an enum:

derive_into_bytes_inner 🔒

derive_into_bytes_struct 🔒

derive_into_bytes_union 🔒

A union is IntoBytes if:

derive_known_layout_inner 🔒

derive_no_cell_inner 🔒

derive_split_at_inner 🔒

derive_try_from_bytes_enum 🔒

derive_try_from_bytes_inner 🔒

derive_try_from_bytes_struct 🔒

A struct is TryFromBytes if:

derive_try_from_bytes_union 🔒

A union is TryFromBytes if:

derive_unaligned_enum 🔒

An enum is Unaligned if:

derive_unaligned_inner 🔒

derive_unaligned_struct 🔒

A struct is Unaligned if:

derive_unaligned_union 🔒

Like structs, a union is Unaligned if:

enum_size_from_repr 🔒

extract_zerocopy_crate 🔒

Attempt to extract a crate path from the provided attributes. Defaults to ::zerocopy if not found.

find_zero_variant 🔒

Returns Ok(index) if variant index of the enum has a discriminant of zero. If Err(bool) is returned, the boolean is true if the enum has unknown discriminants (e.g. discriminants set to const expressions which we can’t evaluate in a proc macro). If the enum has unknown discriminants, then it might have a zero variant that we just can’t detect.

gen_trivial_is_bit_valid_unchecked 🔒 ^⚠

Generates a TryFromBytes::is_bit_valid instance that unconditionally returns true.

normalize_bounds 🔒

Normalizes a slice of bounds by replacing TraitBound::Slf with slf.

try_gen_trivial_is_bit_valid 🔒

Attempts to generate a TryFromBytes::is_bit_valid instance that unconditionally returns true.
