Trait Implementations

impl Bsql for EmptyFragment

fn extend_text(&self, _: &mut String)

Extend s with the SQL text for this fragment

fn extend_params<'v, 'p: 'v>(&'p self, _: &mut Vec<DynToSql<'v>>)

Extend p with the bind parameter values for this fragment

fn extend_locs(&self, _: &mut CodeLocationAccumulator)

Extend la with the bsql macro call code locations

fn mk_sql_text(&self) -> String

Returns the SQL text for this fragment as a String

fn mk_params(&self) -> Vec<&dyn ToSql>

Returns an owned Vec of references to the bind parameter values

fn mk_params_for_exec(&self, sql_text: &str) -> Vec<&dyn ToSql>

Gets ready to execute this statement

impl Clone for EmptyFragment

fn clone(&self) -> EmptyFragment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EmptyFragment

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

Formats the value using the given formatter.

impl Default for EmptyFragment

fn default() -> EmptyFragment

Returns the “default value” for a type.

impl Hash for EmptyFragment

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 Ord for EmptyFragment

fn cmp(&self, other: &EmptyFragment) -> 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 EmptyFragment

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

fn partial_cmp(&self, other: &EmptyFragment) -> 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.
