Struct Attribute 

pub struct Attribute(/* private fields */);

An attribute name or identifier, like :db/id or :pet/name.

Implementations

impl Attribute

pub fn from_ident(ident: &str) -> Self

Copies the given identifier and prepends a : to create an Attribute.

pub fn from_string_unchecked(s: String) -> Self

pub fn from_static(s: &'static str) -> Self

Panics if the attribute is invalid.

Methods from Deref<Target = AttributeRef>

pub fn just_the_identifier(&self) -> &str

Without the leading :.

pub fn as_str(&self) -> &str

The identifier with the leading :.

pub fn tail(&self) -> &str

Everything after the last / in the identifier, or just the identifier if no / is in the attribute.

Trait Implementations

impl AsRef<AttributeRef> for Attribute

fn as_ref(&self) -> &AttributeRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<AttributeRef> for Attribute

fn borrow(&self) -> &AttributeRef

Immutably borrows from an owned value.

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Attribute

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

Formats the value using the given formatter.

impl Deref for Attribute

type Target = AttributeRef

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for Attribute

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Attribute

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

Formats the value using the given formatter.

impl From<Attribute> for Value

fn from(v: Attribute) -> Self

Converts to this type from the input type.

impl<'a> FromSql for Attribute

fn column_result(value: SqlValueRef<'_>) -> FromSqlResult<Self>

Converts SQLite value into Rust value.

impl FromStr for Attribute

type Err = AttributeParseError

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 FromTypeTagAndSqlValue for Attribute

fn from_type_tag_and_sql_value( type_tag: i64, value: SqlValueRef<'_>, ) -> FromSqlResult<Self>

impl Ord for Attribute

fn cmp(&self, other: &Attribute) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Attribute

fn eq(&self, other: &Attribute) -> 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 PartialOrd for Attribute

fn partial_cmp(&self, other: &Attribute) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Attribute

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSql for Attribute

fn to_sql(&self) -> Result<ToSqlOutput<'_>>

Converts Rust value to SQLite value

impl<'a> TryFrom<&'a str> for Attribute

type Error = AttributeParseError

The type returned in the event of a conversion error.

fn try_from(s: &'a str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for Attribute

type Error = AttributeParseError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl TypeTag for Attribute

type Factory = Attribute

Used to help map borrowing and owning instances to a single type. To avoid discriminating between &Value, Value, and ValueRef in cases where we want to treat them the same.

fn type_tag(&self) -> i64

impl Eq for Attribute

impl StructuralPartialEq for Attribute
