Enum TaError 

pub enum TaError {
    BadParam(String),
    OutOfRange(String),
    LibNotInitialized,
    OutOfMemory,
    InternalError(String),
}

本库公开错误类型，对应 TA-Lib TA_RetCode 的语义。

Public error type, corresponding to the semantics of TA-Lib TA_RetCode.

Variants

BadParam(String)

非法参数（对应 TA_BAD_PARAM）。例如时间周期 <= 0。 Invalid parameter (maps to TA_BAD_PARAM), e.g. time period <= 0.

OutOfRange(String)

参数越界（对应 TA_OUT_OF_RANGE）。 Parameter out of range (maps to TA_OUT_OF_RANGE).

LibNotInitialized

库未初始化（对应 TA_LIB_NOT_INITIALIZED）。 Library not initialized (maps to TA_LIB_NOT_INITIALIZED).

OutOfMemory

内存分配失败（对应 TA_ALLOC_ERR）。 Memory allocation failure (maps to TA_ALLOC_ERR).

InternalError(String)

内部错误（对应 TA_INTERNAL_ERROR）。 Internal error (maps to TA_INTERNAL_ERROR).

Trait Implementations

impl Clone for TaError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaError

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

Formats the value using the given formatter.

impl Display for TaError

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

Formats the value using the given formatter.

impl Eq for TaError

impl Error for TaError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for TaError

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

Equality operator ==.

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

Inequality operator !=.
