Crate zpl_toolchain_spec_tables 

ZPL command specification tables.

Defines the data structures for ZPL command metadata, including command entries, argument schemas, constraints, and an opcode trie for fast command recognition. These tables are deserialized from the generated JSON spec and consumed by the parser and validator.

Structs

Arg

Rich metadata for a single command argument.

CommandEntry

Metadata for a single ZPL command (or group of aliased commands).

Composite

Composite parameter group — combines multiple args into a single path-like parameter in the signature (e.g., d:o.x for ^XG).

ConditionalRange

A numeric range that applies only when a predicate is satisfied.

ConditionalRounding

A rounding policy that applies only when a predicate is satisfied.

Constraint

A command-level validation constraint.

ConstraintDefaults

Default values for command-level constraints.

Effects

Describes which cross-command state a command sets.

Example

An executable/documentation example for a command.

FieldDataRules

Validation rules for field data content associated with a barcode command.

OpcodeTrieNode

A node in the opcode trie used for longest-match command recognition.

ParserTables

Top-level container for all ZPL command spec tables.

Placement

Placement rules that refine command location semantics.

ProfileConstraint

Data-driven profile constraint on an arg value. Replaces hardcoded checks like “^PW <= profile.page.width_dots”.

RoundingPolicy

Policy for rounding or quantizing a numeric argument value.

Signature

Describes the parameter signature of a ZPL command.

SplitRule

Rule for splitting a parameter into multiple parts by character count.

StructuralRuleIndex

Generated structural rule pre-index keyed by kind, trigger, and effect.

Enums

ArgPresence

Declares how firmware interprets argument presence/emptiness.

ArgUnion

A command argument definition — either a single Arg or a oneOf union.

CommandCategory

Functional category for a command.

CommandScope

Command scope — determines the lifecycle boundary of the command’s effect.

ComparisonOp

Comparison operators for profile constraints.

ConstraintKind

Constraint kinds for command-level constraints.

ConstraintScope

Evaluation scope for command-level constraints.

ConstraintSeverity

Severity level for constraint diagnostics.

EnumValue

An allowed enum value — either a plain string or a rich object with gates.

FontReferenceAction

Action variant for font-reference structural rules.

MediaModesTarget

Target variant for media-modes structural rules.

NoteAudience

Audience/surface for note diagnostics.

Plane

Command plane — determines where in the ZPL hierarchy the command operates.

PositionBoundsAction

Action variant for position-bounds structural rules.

ResourceKind

Resource family for resourceRef arguments.

RoundingMode

Rounding modes for numeric arguments.

SpacingPolicy

Opcode spacing policy between command code and first argument.

Stability

Stability level for a command.

StructuralRule

Schema-declared structural validation rule payload.

StructuralRuleKind

Schema-declared structural validator rule kinds.

StructuralTrigger

Trigger flags used to pre-index structural rule applicability.

Constants

TABLE_FORMAT_VERSION

Current format version for the spec table JSON schema.
