Struct MaterializedViewDescriptor 

pub struct MaterializedViewDescriptor {
    pub name: String,
    pub source_sql: String,
    pub source_collections: Vec<String>,
    pub refresh_every_ms: Option<u64>,
    pub retention_duration_ms: Option<u64>,
}

Persisted shape of a single CREATE MATERIALIZED VIEW.

The descriptor stores the original SQL source so the body AST can be recovered by re-parsing at boot — this avoids embedding a version-dependent AST serialization in the on-disk catalog, and keeps the rehydrate path symmetric with the user-facing CREATE.

Fields

name: String

View name as declared in CREATE MATERIALIZED VIEW <name>.

source_sql: String

Verbatim SQL source of the CREATE MATERIALIZED VIEW statement. The rehydrate path re-parses this string to recover the body AST.

source_collections: Vec<String>

Source collections referenced by the view body — populated from collect_table_refs(&q.query) at creation time.

refresh_every_ms: Option<u64>

REFRESH EVERY <duration> clause in milliseconds, or None for refresh-on-demand views.

retention_duration_ms: Option<u64>

WITH RETENTION <duration> clause in milliseconds, or None when no retention policy was declared on the view.

Trait Implementations

impl Clone for MaterializedViewDescriptor

fn clone(&self) -> MaterializedViewDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaterializedViewDescriptor

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

Formats the value using the given formatter.

impl PartialEq for MaterializedViewDescriptor

fn eq(&self, other: &MaterializedViewDescriptor) -> 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.
