Struct Reflection

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

Perform reflection on a JsValue

Implementations

impl Reflection

pub fn new(value: JsValue) -> WalletResult<Self>

Initialize Reflection and check if the value is null or undefined

pub fn new_from_str(value: &JsValue, key: &str) -> WalletResult<Self>

Initialize Reflection from the reflection (js_sys::Reflect) of a value by getting the value described by key argument

pub fn new_object() -> Self

Initialize Reflection from a js_sys::Object

pub fn take(self) -> JsValue

Consumes Self and returns a JsValue

pub fn set_object_str(&mut self, key: &str, value: &str) -> WalletResult<&Self>

Adds the key value arguments to the object within Self

pub fn set_object_string_optional( &mut self, key: &str, value: Option<&String>, ) -> WalletResult<&Self>

Adds the key value arguments to the object within Self

pub fn set_object( &mut self, key: &JsValue, value: &JsValue, ) -> WalletResult<&Self>

Adds the key value arguments to the object within Self

pub fn reflect_inner(&self, key: &str) -> WalletResult<JsValue>

Reflect the key from the value of Self and return the reflected value

pub fn string(&self, key: &str) -> WalletResult<String>

Reflect the key from the value of Self and return the reflected value as a String

pub fn get_bytes_from_vec(&self, key: &str) -> WalletResult<Vec<Vec<u8>>>

Reflect the key from the value of Self and return the reflected value as a Vec of Vec of bytes

pub fn into_bytes(self) -> WalletResult<Vec<u8>>

Consume from the value of Self and return it as a Vec of bytes

pub fn reflect_bytes(&self, key: &str) -> WalletResult<Vec<u8>>

Reflect the key from the value of Self and return the reflected value as a Vec of bytes

pub fn byte32array(&self, key: &str) -> WalletResult<[u8; 32]>

Reflect the key from the value of Self and return the reflected value as a 32 byte array

pub fn get_array(&self) -> WalletResult<Array>

Return the value of Self as a js_sys::Array without consuming Self

pub fn get_string(value: &JsValue) -> WalletResult<String>

Return a JsValue as a String

pub fn vec_string(&self, key: &str) -> WalletResult<Vec<String>>

Reflect the key from the value of Self and return the reflected value as a Vec of String

pub fn reflect_js_array(&self, key: &str) -> WalletResult<Array>

Reflect the key from the value of Self and return the reflected value as a Array

pub fn check_is_undefined(value: &JsValue) -> WalletResult<()>

Check if Self is null or undefined

pub fn get_function(&self, key: &str) -> WalletResult<Function>

Reflect a key from value of Self into a Function

pub fn get_inner(&self) -> &JsValue

Get the value of Self without consuming Self

pub fn js_typeof(value: &JsValue) -> String

Check the JS typeof from a JsValue

pub fn into_function(self) -> WalletResult<Function>

Consume Self and return it’s value as a Function

pub fn into_array(self) -> WalletResult<Array>

Consume Self and return it’s value as an Array

Trait Implementations

impl Clone for Reflection

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Reflection

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

Formats the value using the given formatter.

impl Default for Reflection

fn default() -> Self

Returns the “default value” for a type.
