Struct Table 

pub struct Table {
    pub schema: String,
    pub name: String,
    pub description: Option<String>,
    pub is_view: bool,
    pub is_partitioned: bool,
    pub insertable: bool,
    pub updatable: bool,
    pub deletable: bool,
    pub pk_cols: Vec<String>,
    pub unique_constraints: Vec<(String, Vec<String>)>,
    pub columns: ColumnMap,
    pub computed_columns: HashMap<String, ComputedColumn>,
}

A database table or view.

Fields

schema: String

Schema name

name: String

Table/view name

description: Option<String>

Description from comment

is_view: bool

Whether this is a view (vs a table)

is_partitioned: bool

Whether this is a partitioned table.

It behaves as a table for reading and writing, but not for everything: a system column such as xmax cannot be read back from one.

insertable: bool

Whether INSERT is allowed

updatable: bool

Whether UPDATE is allowed

deletable: bool

Whether DELETE is allowed

pk_cols: Vec<String>

Primary key column names

unique_constraints: Vec<(String, Vec<String>)>

Unique constraints, as (name, columns), the primary key among them.

Named because ON CONFLICT ON CONSTRAINT takes a name: an upsert has to say which uniqueness it is resolving against, and a table may have several.

columns: ColumnMap

Columns indexed by name

computed_columns: HashMap<String, ComputedColumn>

Computed columns, indexed by name.

Not part of the table, and never returned by select=*: a function of one argument of the table’s own row type, which PostgreSQL lets a query read as though it were a column. PostgREST exposes them under the name the function has, so ?select=id,always_true and ?always_true=is.true both work on a table that has no such column.

Implementations

impl Table

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

Get a column by name.

pub fn get_computed_column(&self, name: &str) -> Option<&ComputedColumn>

Get a computed column by name.

pub fn has_column(&self, name: &str) -> bool

Check if the table has a column.

pub fn qualified_identifier(&self) -> QualifiedIdentifier

Get the qualified identifier for this table.

pub fn column_names(&self) -> impl Iterator<Item = &str>

Get column names in order.

pub fn is_readonly(&self) -> bool

Check if this is a read-only view.

Trait Implementations

impl Clone for Table

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 Table

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Table

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Table
