A contract claim for one observed values path.

Fields

source_expr: String

Canonical values path or expression that supplied the rendered value.

path: YamlPath

Structural path of the value in the rendered YAML document.

kind: ValueKind

How the value contributes to the rendered YAML node.

condition: GuardDnf

Normalized condition under which the use renders.

resource: Option<ResourceRef>

Kubernetes resource owning the rendered path, when known.

provenance: Vec<ContractProvenance>

Template locations and helper chains that produced the use.

has_string_contract: bool

A string-consuming transform (trunc, b64enc, a dynamic printf format) produced this rendered text: rendering fails for non-string values, but only where THIS row’s condition holds.

template_supplied_member_keys: BTreeSet<String>

Literal member keys the TEMPLATE writes beside this fragment splice in the same mapping (- name: tmp next to toYaml .Values.tmpVolume): the rendered object already has them, so a provider slot’s object requiredness must not re-demand them from the user value.

split_segment: Option<SplitSegmentUse>

Set when the rendered text is one separator-delimited segment of the source string rather than the raw value.

merge_layers: Option<MergeLayersUse>

Set when the value renders as one layer of an ordered merge.

range_key: bool

Set when the rendered text is the collection’s RANGE KEY rather than its value: the sink constrains the key domain only.

nil_omitting: bool

The rendered text is a Sprig quote/squote of the value, which skips nil operands: a missing or null source renders an explicit YAML null into the sink (see ProviderSchemaUse::nil_omitting).

omitted_members: BTreeMap<String, Vec<Guard>>

Literal member keys a guard-scoped omit may remove from the rendered map before the sink reads it. Each key maps to the sound RETAIN guards under which the key certainly survives (the omitting arm certainly did not run); an empty guard list means the key’s survival is undecidable and its sink typing must abstain entirely.

digest: bool

Set when the slot renders fresh text DERIVED from the value (include … | sha256sum checksum annotations): the sink observes neither the value nor its serialization, so the row grants its branch serialized tolerance without claiming a path-wide serialization use.

merge_operand: bool

Set when the value flowed through a Sprig merge call as a DIRECT operand: the operand’s strict map contract rides its own fail implication (keyed on the call’s live gate), so this row never rejects a Helm-falsy input at the base.

Implementations

impl ContractUse

pub fn new( source_expr: String, path: YamlPath, kind: ValueKind, guards: Vec<Guard>, resource: Option<ResourceRef>, ) -> Self

Creates a contract use from one conjunction of guards.

pub fn with_provenances( source_expr: String, path: YamlPath, kind: ValueKind, guards: Vec<Guard>, resource: Option<ResourceRef>, provenance: impl IntoIterator<Item = ContractProvenance>, ) -> Self

Creates a guarded contract use with explicit source provenance.

pub fn with_condition_and_provenances( source_expr: String, path: YamlPath, kind: ValueKind, condition: GuardDnf, resource: Option<ResourceRef>, provenance: impl IntoIterator<Item = ContractProvenance>, ) -> Self

Creates a contract use from an already-normalized condition.

pub fn canonicalize(&mut self)

Sorts and deduplicates provenance without changing semantic evidence.

pub fn single_guard_conjunction(&self) -> Vec<Guard>

Returns the sole guard conjunction, or an empty conjunction when not singular.

pub fn map_value_paths<F>(&mut self, map: &mut F)

where F: FnMut(&str) -> String,

Rewrites the source expression and every values path in the condition.
