easypdf-rust 的核心错误类型。

涵盖 I/O、解析、加密和不支持的功能错误。

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

包装标准 I/O 错误。

Parse(String)

PDF 无法解析或包含格式错误的数据。

InvalidPage(usize)

页索引超出范围。

UnsupportedFeature(String)

请求的功能尚未实现或不被引擎支持。

Encryption(String)

PDF 已加密且未提供密码或密码错误。

ResourceLimitExceeded

配置的资源限制被超出。

Fields

resource: &'static str

资源名称。

limit: u64

配置的限制值。

actual: u64

实际观测值。

SecurityViolation(String)

安全守卫拒绝了输入（解压炸弹、SSRF 等）。

Signature(String)

数字签名操作失败。

Other(String)

其他错误的兜底变体。

Implementations

impl PdfError

pub const fn code(&self) -> PdfErrorCode

返回稳定的机器可读错误码。

Trait Implementations

impl Debug for PdfError

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

Formats the value using the given formatter.

impl Display for PdfError

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

Formats the value using the given formatter.

impl Error for PdfError

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 From<Error> for PdfError

fn from(source: Error) -> Self

Converts to this type from the input type.
