Block metadata

Fields

semantic_role: Option<SemanticRole>

Semantic role in document structure

label: Option<String>

Human-readable label

tags: Vec<String>

Searchable tags

summary: Option<String>

Pre-computed summary for folding/context management

content_hash: ContentHash

Content hash for change detection

created_at: DateTime<Utc>

Creation timestamp

modified_at: DateTime<Utc>

Last modification timestamp

custom: HashMap<String, Value>

Custom key-value metadata

Implementations

impl BlockMetadata

pub fn new(content_hash: ContentHash) -> Self

Create new metadata with current timestamp

pub fn with_role(self, role: SemanticRole) -> Self

Set semantic role

pub fn with_label(self, label: impl Into<String>) -> Self

Set label

pub fn with_tag(self, tag: impl Into<String>) -> Self

Add a tag

pub fn with_tags( self, tags: impl IntoIterator<Item = impl Into<String>>, ) -> Self

Add multiple tags

pub fn with_summary(self, summary: impl Into<String>) -> Self

Set summary

pub fn with_custom(self, key: impl Into<String>, value: Value) -> Self

Set custom metadata

pub fn touch(&mut self)

Update modification timestamp

pub fn has_tag(&self, tag: &str) -> bool

Check if block has a specific tag

Trait Implementations

impl Clone for BlockMetadata

fn clone(&self) -> BlockMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlockMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BlockMetadata

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BlockMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BlockMetadata

fn eq(&self, other: &BlockMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BlockMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
