Struct PgLTree 

pub struct PgLTree(pub String);

PostgreSQL LTREE type – a dot-separated label path for hierarchical data.

LTREE is a PostgreSQL extension type used for representing labels of data stored in a hierarchical tree-like structure. Example: "top.science.astronomy".

Wire format: UTF-8 text bytes (same as TEXT). Uses TEXT OID as carrier since LTREE is an extension type without a stable OID.

Trait Implementations

impl Clone for PgLTree

fn clone(&self) -> PgLTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PgLTree

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

Formats the value using the given formatter.

impl Display for PgLTree

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

Formats the value using the given formatter.

impl FromSql for PgLTree

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 FromStr for PgLTree

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for PgLTree

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 PgLTree

fn eq(&self, other: &PgLTree) -> 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 PgLTree

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.

impl Eq for PgLTree
