ViewReader

Struct ViewReader 

Source
#[non_exhaustive]
pub struct ViewReader { pub kind: ReaderKind, pub schema: Option<String>, pub name: String, pub relation: String, pub parameter_types: Vec<String>, }
Expand description

One object Razeri makes later in the same file that reads a view.

Every name arrives spelled as the statements write it: quoted where the dialect quotes, and qualified.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§kind: ReaderKind

What kind of object it is.

§schema: Option<String>

Its schema, as the statements write it, where it has one.

§name: String

Its own name, as the statements write it.

§relation: String

The schema and the name, qualified as the statements write them.

§parameter_types: Vec<String>

A routine’s parameter types, in order, spelled as its CREATE spells them; empty for a view and for a routine that takes none.

Implementations§

Source§
