PartitionKeySchemaV1

laminar_core::state::partition_key

Struct PartitionKeySchemaV1 

Source 
pub struct PartitionKeySchemaV1 { /* private fields */ }
Expand description

Persistable routing identity for an ordered partition-key schema.

The descriptor is opaque. Its bytes are a persisted ABI and may only change with an explicit partition-key schema version decision and new goldens.

Implementations§

Source§

impl PartitionKeySchemaV1

Source

pub fn try_new(fields: &[FieldRef]) -> Result<Self, PartitionKeyCodecError>

Validate and describe one ordered, resolved partition-key schema.

Dictionary index widths are physical transport details and recursively hydrate to the value type. Field names are SQL aliases and are omitted; order and nullability remain identity.

§Errors

Returns an error for an empty, over-wide, metadata-bearing, unsupported, over-nested, or over-sized routing schema.

Source

pub fn as_bytes(&self) -> &[u8] ⓘ

Canonical, versioned routing-schema bytes.

Source

pub const fn sha256(&self) -> [u8; 32]

SHA-256 of Self::as_bytes.
