Crate brink_format 

Binary interface between the brink compiler and runtime.

This crate defines the types shared across the compiler/runtime boundary: DefinitionId, opcodes, value types, line templates, and the top-level StoryData container.

brink-runtime depends ONLY on this crate — nothing else from brink.

Structs

AddressDef

An address pointing to a specific byte offset within a container.

AddressPath

Maps a qualified author path (e.g. knot, knot.stitch, knot.label, knot.stitch.label) to the DefinitionId it addresses.

ChoiceFlags

Flags packed into a BeginChoice instruction.

ContainerDef

A compiled container (knot, stitch, gather, or anonymous flow block).

CountingFlags

Flags controlling what the runtime counts for a container.

DefinitionId

A tagged 64-bit identifier for any definition in a compiled story.

ExternalFnDef

An externally-bound function definition.

GlobalVarDef

A global variable definition.

InkbIndex

Parsed header + offset table from an .inkb file.

InktParseError

Error returned when parsing .inkt text fails.

LineEntry

One entry in a container’s line table.

LineFlags

Whitespace characteristics of a line, precomputed at compile time.

LineId

A reference to a specific line within a container.

ListDef

A list (enum-like set) definition.

ListItemDef

A single list item definition.

ListValue

An ink list value: a set of list items plus their origin list definitions.

LocaleData

Complete locale overlay data from a .inkl file.

LocaleLineEntry

A locale line entry — content + optional audio, no source metadata.

LocaleScopeTable

A per-scope locale line table.

NameId

An index into the story name table.

ScopeLineTable

Per-scope line table, stored separately from ContainerDef for locale overlay swapping (.inkl).

SectionEntry

An entry in the .inkb offset table.

SlotInfo

Metadata for a single interpolation slot in a template line.

SourceLocation

Source location of a line in the original .ink file.

StoryData

The top-level compiled story: everything the runtime needs to execute.

Enums

DecodeError

Errors that can occur when decoding from bytes.

DefinitionTag

Tag discriminant stored in the high byte of a DefinitionId.

LineContent

The content of a single output line — either a plain string or a template with interpolation slots and plural selects.

LinePart

One segment of a LineTemplate.

Opcode

A single VM instruction with its operands.

PluralCategory

CLDR plural category.

SectionKind

Identifies a section within an .inkb file.

SelectKey

The key for matching a branch in a LinePart::Select.

SequenceKind

The kind of sequence/shuffle container.

Value

A runtime value in the ink VM.

ValueType

The runtime type of a Value.

Traits

PluralResolver

Trait for resolving plural categories at runtime.
