Why a nichlink.trace document was refused. nichlink.trace 文档被拒绝的原因。

Variants

UnsupportedVersion(u32)

Document declares a layout this build cannot read. 文档声明的版式是本构建读不懂的。

MissingKey(&'static str)

Document omitted a required scalar key. 文档缺少一个必需的标量键。

UnknownKey(String)

Document carried a key this format does not define. 文档带有本格式未定义的键。

Malformed

Document had a line, field count, or escape the format cannot read. 文档中存在本格式读不懂的行、字段数或转义。

Fields

line: usize

1-based line the failure was found on. 发现失败的行号，从 1 起。

message: String

What was wrong with that line. 该行错在哪里。

DuplicateFrame(u64)

Two frames carry the same id. 两个调用帧使用了同一个 id。

DuplicateLocal(u64)

Two locals carry the same id. 两个局部值使用了同一个 id。

MissingParent(u64)

A frame names a parent frame the document does not contain. 某个调用帧指名的父帧不在文档中。

DanglingEdge

An edge endpoint has no local in the document. 某条边的端点没有对应的局部值。

Fields

from: u64

The local id the edge leaves. 该边离开的局部值 id。

to: u64

The local id the edge enters. 该边进入的局部值 id。

impl Eq for TraceArtifactError

impl Error for TraceArtifactError

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.
