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 as key-value pairs. How to use the context is custom to the specific implementation. On a request, it carries caller-provided context to the implementation. On a response, it carries implementation-provided context back to the caller. REST NAMESPACE ONLY Context entries are mapped to and from HTTP headers using the header. prefix: - On a request, any entry whose key starts with header. is sent as an HTTP request header with the prefix stripped. For example, the entry {\"header.Authorization\": \"Bearer abc\"} is sent as the request header Authorization: Bearer abc. - On a response, every HTTP response header is returned as an entry whose key is the header name prefixed with header.. For example, the response header x-request-id: abc123 is returned as the entry {\"header.x-request-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
