Struct PgBit 

pub struct PgBit {
    pub data: Vec<u8>,
    pub bit_length: i32,
}

PostgreSQL BIT / VARBIT type.

Stores a fixed- or variable-length bit string. data holds raw bytes (MSB-first, padded with trailing zeros in the last byte). bit_length is the actual number of significant bits.

Fields

data: Vec<u8>

bit_length: i32

Implementations

impl PgBit

pub fn from_bools(bits: &[bool]) -> Self

Create from a slice of bools (true = 1, false = 0).

pub fn get(&self, index: usize) -> Option<bool>

Get the bit at the given index (0-based, MSB-first).

pub fn len(&self) -> usize

Number of bits.

pub fn is_empty(&self) -> bool

True if zero bits.

Trait Implementations

impl Clone for PgBit

fn clone(&self) -> PgBit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgBit

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

Formats the value using the given formatter.

impl FromSql for PgBit

fn oid() -> Oid

The PostgreSQL type OID this decoder handles.

fn from_sql(buf: &[u8]) -> Result<Self>

Decode from PG binary format.

fn from_sql_nullable(buf: Option<&[u8]>) -> Result<Self>

Decode from a potentially NULL column.

impl Hash for PgBit

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PgBit

fn eq(&self, other: &PgBit) -> 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.

impl ToSql for PgBit

fn oid(&self) -> Oid

The PostgreSQL type OID for this Rust type.

fn to_sql(&self, buf: &mut BytesMut) -> Result<()>

Encode this value into PG binary format, appending to buf.

fn to_sql_vec(&self) -> Result<Vec<u8>>

Encode this value into a standalone byte vector for use as a bind parameter.

fn is_null(&self) -> bool

Returns true if this value represents SQL NULL.
