Struct UpdateTableRequest 

pub struct UpdateTableRequest {
    pub identity: Option<Box<Identity>>,
    pub context: Option<HashMap<String, String>>,
    pub id: Option<Vec<String>>,
    pub branch: Option<String>,
    pub predicate: Option<String>,
    pub updates: Vec<Vec<String>>,
    pub properties: Option<HashMap<String, String>>,
}

UpdateTableRequest : Each update consists of a field path and an SQL expression that will be evaluated against the current row’s value. Optionally, a predicate can be provided to filter which rows to update.

Fields

identity: Option<Box<Identity>>

context: Option<HashMap<String, String>>

Arbitrary context for a request as key-value pairs. How to use the context is custom to the specific implementation. REST NAMESPACE ONLY Context entries are passed via HTTP headers using the naming convention x-lance-ctx-<key>: <value>. For example, a context entry {\"trace_id\": \"abc123\"} would be sent as the header x-lance-ctx-trace_id: abc123.

id: Option<Vec<String>>

branch: Option<String>

Branch to target. When not specified, the main branch is used.

predicate: Option<String>

Optional SQL predicate to filter rows for update. Field references must use Lance field path syntax: nested fields use dot-separated segments, literal dots require backtick-quoted segments, and backticks inside quoted segments are doubled.

updates: Vec<Vec<String>>

List of field updates as [field_path, expression] pairs. Field paths and expression references must use Lance field path syntax: nested fields use dot-separated segments, literal dots require backtick-quoted segments, and backticks inside quoted segments are doubled.

properties: Option<HashMap<String, String>>

Properties stored on the table, if supported by the implementation.

Implementations

impl UpdateTableRequest

pub fn new(updates: Vec<Vec<String>>) -> UpdateTableRequest

Each update consists of a field path and an SQL expression that will be evaluated against the current row’s value. Optionally, a predicate can be provided to filter which rows to update.

Trait Implementations

impl Clone for UpdateTableRequest

fn clone(&self) -> UpdateTableRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateTableRequest

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

Formats the value using the given formatter.

impl Default for UpdateTableRequest

fn default() -> UpdateTableRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UpdateTableRequest

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UpdateTableRequest

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

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.
