Struct Unit 

pub struct Unit {
    pub name: &'static str,
    pub kind: UnitKind,
    pub identity_path: &'static str,
    pub source: &'static str,
    pub binding: Binding,
    pub id_block: u32,
    pub platform: Option<Platform>,
    pub env_providers: &'static [&'static str],
    pub stability: Stability,
    pub experimental: &'static [&'static str],
    pub extensible: &'static [&'static str],
    pub instantiable: &'static [Instantiable],
}

One first-party unit, as data (standard-library track, S1 #1945). Adding a unit to the standard library is an entry in UNITS plus its files; the checker’s injection reads this table and needs no change.

Fields

name: &'static str

The unit’s dotted name, inside the reserved bynk.* prefix.

kind: UnitKind

Whether a project consumes it (an adapter) or uses it (a commons).

identity_path: &'static str

The synthetic path the injected unit is parsed under. Diagnostics and emission name the unit by it, so it never changes.

source: &'static str

The unit’s .bynk source.

binding: Binding

The binding the toolchain supplies for it.

id_block: u32

Its permanent ExprId block: the checker parses it at FIRSTPARTY_ID_BASE + id_block * FIRSTPARTY_ID_BLOCK, and injects units in ascending id_block order. A block is never reused or moved, so ids and injection order stay stable as units are added; a new unit takes the next free block.

platform: Option<Platform>

The platform that consuming it locks a deployment unit to (decision 0024), if it is platform-native.

env_providers: &'static [&'static str]

The provider classes whose constructor takes the Worker env (decisions 0021/0025).

stability: Stability

The unit’s stability (track D2, S3 #1963): a stable item is under the 1.0 promise, an experimental one carries none and needs an explicit [unstable] allow to use. Required, so no entry is added without a choice.

experimental: &'static [&'static str]

Items inside a stable unit that are experimental, as paths relative to the unit: an exported item ("Kv") or a capability operation ("Kv.list"). An experimental item makes its operations experimental.

extensible: &'static [&'static str]

The exported enums that may gain variants in a minor release, so a match covering one needs a wildcard (track §11 Q5).

instantiable: &'static [Instantiable]

The capabilities a context may declare named instances of with capability Sessions = Kv (S4a, #1966): each its own platform resource. A capability not listed (Workers AI’s single [ai] binding, say) has no instances.

Implementations

impl Unit

pub fn binding_for( &self, platform: Platform, ) -> Option<(&'static str, &'static str)>

The binding module to emit for this unit on platform, as (output path, source), or None for a commons.

Trait Implementations

impl Clone for Unit

fn clone(&self) -> Unit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Unit

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Unit

fn eq(&self, other: &Unit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
