Struct Table 

pub struct Table {
    pub name: Arc<str>,
    pub columns: Vec<Column>,
    pub source: Source,
    pub cardinality: Cardinality,
    pub element: Arc<str>,
}

Fields

name: Arc<str>

columns: Vec<Column>

source: Source

cardinality: Cardinality

element: Arc<str>

The Beck type one row stands for, for beck explain sql to print.

Implementations

impl Table

pub fn column(&self, name: &str) -> Option<(usize, &Column)>

pub fn row(&self, v: &Value) -> Vec<Cell>

One value as one row, coerced to the columns this table declares.

Coerced rather than trusted: the column types come from the declared type and the value comes from a running program, so a value that does not fit its column becomes NULL rather than a wrongly-encoded field on the wire. Nothing in the corpus reaches that branch; the branch is there because “cannot happen” is not a wire format.

Trait Implementations

impl Clone for Table

fn clone(&self) -> Table

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Table

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

Formats the value using the given formatter.
