Struct BithumbAuth

pub struct BithumbAuth { /* private fields */ }

Bithumb authentication handler

Implementations

impl BithumbAuth

pub const fn new(api_key: SmartString, api_secret: SmartString) -> Self

Create new Bithumb auth instance

pub fn build_param_string_optimized( params: &[(&str, &str)], ) -> Result<SmartString>

Optimized parameter string building using SmallVec for stack allocation Uses SmallVec<[SmartString; 8]> to avoid heap allocation for typical parameter counts Enhanced with auth module’s optimized implementation

Important: Bithumb’s API specification requires parameters to be sorted alphabetically by key name for signature verification. This implementation processes parameters in their input order for performance optimization.

Note: Ensure parameters are pre-sorted before calling this function if signature verification is required, as mandated by Bithumb’s API.

pub fn generate_nonce() -> SmartString

Generate API nonce (UUID v4)

pub fn generate_timestamp() -> u64

Generate timestamp in milliseconds

pub fn generate_timestamp_nanos() -> u128

Generate timestamp in nanoseconds for high-precision timing

pub fn encode_params_zero_copy( params: &str, buffer: &mut SmartString, ) -> Result<()>

URL-encode the provided parameter string using a pre-allocated buffer.

This performs zero-copy encoding to avoid unpredictable heap allocations on critical paths.

pub fn generate_headers( &self, _method: &str, _path: &str, params: Option<&[(&str, &str)]>, ) -> Result<FxHashMap<SmartString, SmartString>>

Generates authentication headers for a request.

pub fn generate_headers_for_json_body( &self, json_body: &str, ) -> Result<FxHashMap<SmartString, SmartString>>

Generate headers for JSON body requests (POST/PUT/DELETE)

Bithumb API requires:

• Request body in JSON format
• Authentication hash calculated from URL-encoded representation of JSON parameters
• Content-Type: application/json; charset=utf-8

pub fn build_query_string(params: &[(&str, &str)]) -> Result<SmartString>

Generate query string from parameters (optimized version using auth module)

Important: Bithumb’s API specification requires parameters to be sorted alphabetically by key name for signature verification. However, this implementation currently uses natural order (no sorting) for performance optimization.

Note: If signature verification fails, ensure parameters are pre-sorted before calling this function, as required by Bithumb’s API documentation.

pub fn param_count(params: Option<&[(&str, &str)]>) -> usize

Fast parameter count for pre-allocation decisions

pub fn generate_ws_auth(&self) -> Result<SmartString>

Generate WebSocket authentication message Bithumb WebSocket uses PING/PONG for connection management

pub fn generate_joined_param(params: &[(&str, &str)]) -> Option<SmartString>

Generate joined parameter string (for backward compatibility)

pub fn api_key(&self) -> &str

Get API key
