Struct Constraints 

pub struct Constraints {
    pub keys: Vec<(Vec<u16>, bool)>,
    pub foreign: Vec<StoredForeign>,
}

A table’s primary, unique and foreign keys, as the file stores them.

Columns are places in the table, and a foreign key names the table it points at by name alone, because every table in one file is in one schema.

Fields

keys: Vec<(Vec<u16>, bool)>

Each key’s columns, and whether it is the primary key rather than a unique one.

foreign: Vec<StoredForeign>

Each foreign key.

Implementations

impl Constraints

pub fn is_empty(&self) -> bool

Whether there is nothing here, which is what writes no block.

Trait Implementations

impl Clone for Constraints

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constraints

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

Formats the value using the given formatter.

impl Default for Constraints

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Constraints

impl PartialEq for Constraints

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
