Struct UpdateFieldMetadataEntry 

pub struct UpdateFieldMetadataEntry {
    pub path: String,
    pub metadata: HashMap<String, String>,
    pub replace: Option<Option<bool>>,
}

Fields

path: String

Lance field path whose metadata to update. Nested fields use dot-separated segments; use backtick-quoted segments for literal dots and double backticks inside quoted segments. Use canonical full paths for display and errors; leaf names alone only identify top-level fields; invalid or unresolved paths should return InvalidInput or TableColumnNotFound.

metadata: HashMap<String, String>

Metadata key-value pairs to apply to the field. A null value deletes that key.

replace: Option<Option<bool>>

If true, replace the field’s existing metadata entirely; otherwise merge into it (optional, defaults to false).

Implementations

impl UpdateFieldMetadataEntry

pub fn new( path: String, metadata: HashMap<String, String>, ) -> UpdateFieldMetadataEntry

Trait Implementations

impl Clone for UpdateFieldMetadataEntry

fn clone(&self) -> UpdateFieldMetadataEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateFieldMetadataEntry

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

Formats the value using the given formatter.

impl Default for UpdateFieldMetadataEntry

fn default() -> UpdateFieldMetadataEntry

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UpdateFieldMetadataEntry

fn deserialize<__D>( __deserializer: __D, ) -> Result<UpdateFieldMetadataEntry, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UpdateFieldMetadataEntry

fn eq(&self, other: &UpdateFieldMetadataEntry) -> 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 UpdateFieldMetadataEntry

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
