Struct PrimaryKey 

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

Available on crate feature std only.

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

impl PrimaryKey

pub fn new( table: impl Into<Cow<'static, str>>, name: impl Into<Cow<'static, str>>, columns: impl Into<Cow<'static, [Cow<'static, str>]>>, ) -> PrimaryKey

Available on crate features alloc or std only.

Create a new primary key with owned data

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

Available on crate features alloc or std only.
