Struct CompiledBlock 

pub struct CompiledBlock {
    nodes: Vec<Node>,
    bytecode: Option<CompiledBytecode>,
}

A pre-compiled block of expressions ready to execute against a MilkContext. See module docs.

Fields

nodes: Vec<Node>

bytecode: Option<CompiledBytecode>

Implementations

impl CompiledBlock

pub fn from_nodes(nodes: Vec<Node>, ctx: &mut MilkContext) -> Self

Take ownership of nodes and try to lower them to bytecode against ctx. Cold-variable names referenced by the block are interned into ctx.cold so the emitted opcodes carry slab indices.

On lowering failure (any unsupported operator/function) the block stores bytecode: None and the runtime falls back to evalexpr’s tree-walking interpreter — same observable behaviour, just slower.

pub fn empty() -> Self

Empty block — run is a no-op.

pub fn nodes(&self) -> &[Node]

Underlying evalexpr nodes. Always populated, even when bytecode is also available (kept around as the fallback path for the few runtime decisions that need per-node access — e.g. per-equation error logging).

pub fn bytecode(&self) -> Option<&CompiledBytecode>

Bytecode lowering when available. None means at least one node uses an op the VM doesn’t support; runtime falls back to the Nodes path.

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn run(&self, ctx: &mut MilkContext)

Execute the block against ctx. Prefers the bytecode VM when available; otherwise iterates the evalexpr nodes and discards per-equation errors silently. Call sites that want to log per-equation failures should use CompiledBlock::nodes + CompiledBlock::bytecode directly.
