PrimaryKey

Struct PrimaryKey 

Source
pub struct PrimaryKey {
    pub table: Cow<'static, str>,
    pub name: Cow<'static, str>,
    pub columns: Cow<'static, [Cow<'static, str>]>,
    pub name_explicit: bool,
}
Expand description

Runtime primary key constraint entity

Uses Cow<'static, str> for all string fields, which works with both:

  • Borrowed data from const definitions (Cow::Borrowed)
  • Owned data from deserialization/introspection (Cow::Owned)

Fields§

§table: Cow<'static, str>

Parent table name

§name: Cow<'static, str>

Constraint name

§columns: Cow<'static, [Cow<'static, str>]>

Columns in the primary key

§name_explicit: bool

Whether the constraint name was explicitly specified

Implementations§

Source§

impl PrimaryKey

Source

pub fn from_strings( table: String, name: String, columns: Vec<String>, ) -> PrimaryKey
