Struct JsonPathIdentityV1 

pub struct JsonPathIdentityV1 {
    pub root: JsonPathRootV1,
    pub segments: Vec<PathSeg>,
}

Versioned structural identity for a query JSON path. Unlike the stored table-local form, this retains a qualified root until binding resolves it.

Fields

root: JsonPathRootV1

segments: Vec<PathSeg>

Implementations

impl JsonPathIdentityV1

pub const VERSION: u8 = 1

pub fn from_expr(expr: &Expr) -> Option<Self>

pub fn canonical_bytes(&self) -> Vec<u8>

pub fn canonical_text(&self) -> String

pub fn bind_table_local( &self, qualifier: Option<&str>, ) -> Option<StoredJsonPathV1>

Bind an unqualified root, or a qualified root matching qualifier, to the storage-owned table-local identity used by future expression-index catalog entries.
