#[non_exhaustive]
pub struct FieldDescription { /* private fields */ }

Metadata describing a single column in a query result.

Implementations

impl FieldDescription

pub fn new( name: String, table_oid: Oid, column_id: i16, type_oid: Oid, type_size: i16, type_modifier: i32, format: i16, ) -> Self

Create a new field description.

pub fn name(&self) -> &str

Column name.

pub fn table_oid(&self) -> Oid

Table OID.

pub fn column_id(&self) -> i16

Column ID within the table.

pub fn type_oid(&self) -> Oid

Data type OID.

pub fn type_size(&self) -> i16

Type size.

pub fn type_modifier(&self) -> i32

Type modifier.

pub fn format(&self) -> i16

Format code.

Trait Implementations

impl Clone for FieldDescription

fn clone(&self) -> FieldDescription

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldDescription

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

Formats the value using the given formatter.

impl PartialEq for FieldDescription

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
