Struct ChainId 

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

Identifies the NEAR chain the client is connected to.

This is a string-based newtype that replaces the former Network enum, allowing any chain identifier (not just the hardcoded variants).

Use the named constructors for well-known chains, or ChainId::new for custom ones.

Examples

use near_kit::ChainId;

let mainnet = ChainId::mainnet();
assert!(mainnet.is_mainnet());
assert_eq!(mainnet.as_str(), "mainnet");

let custom = ChainId::new("localnet");
assert_eq!(custom.as_str(), "localnet");

Implementations

impl ChainId

pub fn new(id: impl Into<String>) -> Self

Create a chain ID from any string.

pub fn mainnet() -> Self

NEAR mainnet.

pub fn testnet() -> Self

NEAR testnet.

pub fn is_mainnet(&self) -> bool

Returns true if this is mainnet.

pub fn is_testnet(&self) -> bool

Returns true if this is testnet.

pub fn as_str(&self) -> &str

Returns the chain identifier as a string slice.

Trait Implementations

impl AsRef<str> for ChainId

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ChainId

fn clone(&self) -> ChainId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainId

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

Formats the value using the given formatter.

impl Default for ChainId

fn default() -> Self

Returns the “default value” for a type.

impl Display for ChainId

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

Formats the value using the given formatter.

impl From<&str> for ChainId

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for ChainId

fn from(s: String) -> Self

Converts to this type from the input type.

impl Hash for ChainId

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ChainId

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
