Compiler

Struct Compiler

pub struct Compiler;

Implementations§

impl Compiler

pub fn compile(query: &ResolvedQuery, stats: &GraphStats) -> CompiledQuery

Compile a resolved query into an executable plan, using stats for cost-based rewrite selection. Pass GraphStats::default() when no cardinality information is available — the optimizer then falls back to the conservative “commit any matching rewrite” behaviour that the runtime executor handles safely.

Blanket Implementations§

impl<T> Any for T

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T, U> TryFrom<U> for T
where U: Into<T>,

type Error = !

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, !>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.
