impl Debug for FileReader

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

Formats the value using the given formatter.

impl Default for FileReader

fn default() -> FileReader

Returns the “default value” for a type.

impl<'cx> FromValue<'cx> for &'cx FileReader

type Config = ()

fn from_value( cx: &'cx Context, value: &Value<'_>, strict: bool, _: (), ) -> Result<&'cx FileReader>

Converts value to the desired type. strict and config determine the strictness of the conversion and specify additional conversion constraints respectively. Returns Err with the error if conversion fails.

impl<'cx> FromValue<'cx> for &'cx mut FileReader

type Config = ()

fn from_value( cx: &'cx Context, value: &Value<'_>, strict: bool, _: (), ) -> Result<&'cx mut FileReader>

Converts value to the desired type. strict and config determine the strictness of the conversion and specify additional conversion constraints respectively. Returns Err with the error if conversion fails.

impl NativeObject for FileReader

fn reflector(&self) -> &Reflector

impl Traceable for FileReader

unsafe fn trace(&self, __ion_tracer: *mut JSTracer)

Trace self.

impl DerivedFrom<Reflector> for FileReader

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
