Struct Params 

pub struct Params<'a>(/* private fields */);

Parameters sent with an incoming JSON-RPC request.

The data containing the params is a Cow<&str> and can either be a borrowed &str of JSON from an incoming super::request::Request (which in turn borrows it from the input buffer that is shared between requests); or, it can be an owned String.

Implementations

impl<'a> Params<'a>

pub fn new(raw: Option<&'a str>) -> Self

Create params

pub fn sequence(&self) -> ParamsSequence<'_>

Obtain a sequence parser, ParamsSequence.

This allows sequential parsing of the incoming params, using an Iterator-style API and is useful when the RPC request has optional parameters at the tail that may or may not be present.

pub fn parse<T>(&'a self) -> Result<T, ErrorObjectOwned>

where T: Deserialize<'a>,

Attempt to parse all parameters as an array or map into type T.

pub fn one<T>(&'a self) -> Result<T, ErrorObjectOwned>

where T: Deserialize<'a>,

Attempt to parse parameters as an array of a single value of type T, and returns that value.

pub fn into_owned(self) -> Params<'static>

Convert Params<'a> to Params<'static> so that it can be moved across threads.

This will cause an allocation if the params internally are using a borrowed JSON slice.

pub fn len_bytes(&self) -> usize

Return the length of underlying JSON string in number of bytes.

pub fn as_str(&self) -> Option<&str>

Return the underlying JSON string as a &str.

Trait Implementations

impl<'a> Clone for Params<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Params<'a>

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

Formats the value using the given formatter.

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.
