Traits

traitWIntKeyTag

trait WIntKeyTag

Supplies the per-key Writ wire tag (MapI32AnyVal=3101 .. MapU64AnyVal=3104).

Implemented by: i32 u32 i64 u64

traitWritField

trait WritField

Converts schema field values between WAny and Self (the seam behind schema field sugar). Implementing it makes a type schema-storable; generic schemas resolve it at monomorphization.

Types

structWMap

struct WMap

Anchors the WMap<K, V> family as an empty base; never instantiated directly. Per-key-shape partial specialisations attach layout and impls (mirrors legacy Map<K,V>).

Methods

fn cap(self: &WMap<Wu6, WAny>) -> i64

Returns the fixed slot capacity (max 52).

fn contains(self: &WMap<Wu6, WAny>, key: u8) -> bool

Returns true if key is present.

fn get(self: &WMap<Wu6, WAny>, key: u8) -> WAny

Returns the value at key, or a null WAny if absent or key >= 52.

fn get_mut(self: &mut WMap<WString, WAny>, key: &[u8]) -> WAnyMut

Returns a mutable cursor onto the value at key, carrying this map’s zone. The cursor’s slot is null when key is absent — callers must ensure the key exists.

fn key_at(self: &WMap<WString, WAny>, i: i64) -> WAny

Returns the key at slot i (interned WString Ref); null WAny if the slot is empty.

fn len(self: &WMap<WString, WAny>) -> i64

Returns the number of entries.

fn schema_type_code(self: &WMap<Wu6, WAny>) -> u64

Returns the node-class discriminator (0 = none); byte-shared with the C++ TinyObjectMap.

fn set(self: &mut WMap<Wu6, WAny>, key: u8, val: WAny) -> void

Inserts or updates key → val; key >= 52 is a silent no-op. Panics when a NEW key would exceed the fixed capacity (over-capacity insert = bounds error).

fn set_schema_type_code(self: &mut WMap<Wu6, WAny>, code: u64) -> void

Sets the node-class discriminator.

fn size(self: &WMap<Wu6, WAny>) -> i64

Returns the number of present entries.

fn slots(self: &WMap<WString, WAny>) -> i64

Returns the slot count (cap) for raw slot iteration over 0..slots().

fn val_at(self: &WMap<WString, WAny>, i: i64) -> WAny

Returns the value at slot i; null WAny if the slot is empty.

structWMapEntry

struct WMapEntry

Stores one open-addressing slot: two at-rest WAny words (key @0, val @8).

Fields

key: i64

At-rest Ref to the interned WString key; 0 marks an empty slot.

val: i64

The stored value as an at-rest WAny word.

structWSchemaH

struct WSchemaH

Carries the runtime shape of a schema view: TOM pointer + arena allocator (ADR 0011). The compiler’s view type S has this exact layout; make::<S>() retypes WSchemaH to S.

Fields

m: *const WMap<Wu6, WAny>

The underlying TOM (WMap<Wu6, WAny>) header.

z: *mut u8

Arena allocator for boxing wide values on write.

structWu6

struct Wu6

Labels the 6-bit key (keys 0..51) at the type level. The bitmap-indexed map is WMap<Wu6, WAny>, aliased WTinyValMap.
