Implementations

impl Features

pub fn new() -> Self

Returns a feature set with "default" silkworm extensions enabled. Same as Default::default.

pub fn basic() -> Self

Returns a feature set with everything disabled except pragmas.

Features can still be turned on at the file level using feature pragmas.

pub fn compatible() -> Self

Returns a feature set that is intended to be compatible with YarnSpinner 1.1.

This disables everything including pragmas. Features cannot be turned on at the file level.

pub fn all() -> Self

Returns a feature set with everything enabled.

Trait Implementations

impl Clone for Features

fn clone(&self) -> Features

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl Default for Features

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Features

impl Hash for Features

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, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<Features> for Features

fn eq(&self, other: &Features) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Features) -> bool

This method tests for !=.
