Struct DeferredExpression 

pub struct DeferredExpression(/* private fields */);

Bounded flat concatenation with per-segment provenance.

Unset or empty references contribute an empty string to container environment assignments. Host-bind expressions additionally require a nonempty absolute effective source with no colon or control characters. These are external prerequisites, not runtime verification.

Implementations

impl DeferredExpression

pub fn new(parts: Vec<Sourced<DeferredSegment>>) -> Result<Self, ModelError>

Creates an expression containing at least one explicit reference.

Errors

Returns a value-free error for NUL, size limits, or missing references.

pub fn segments(&self) -> &[Sourced<DeferredSegment>]

Returns segments in concatenation order.

pub fn has_nonempty_literal(&self) -> bool

Returns whether output needs explicit environment-value disclosure authorization.

pub fn validate_host_bind(&self) -> Result<(), ModelError>

Validates one leading direct reference and a safe optional slash suffix.

Errors

Returns a value-free error for unsupported host-bind shapes or unsafe delimiters.
