Enum VclError

pub enum VclError {
    String(String),
    Str(&'static str),
    CStr(&'static CStr),
    WsOutOfMemory(NonZeroUsize),
    Utf8Error(Utf8Error),
    Box(Box<dyn Error>),
}

An Error describing all issues with the VCL module

This enum is used to describe all the possible errors that can happen when working with the VCL module, or converting between Rust and C types.

Variants

String(String)

Create a new Error from a string

Str(&'static str)

Create a new Error from a string slice

CStr(&'static CStr)

Create a new VclError from a C string

WsOutOfMemory(NonZeroUsize)

In case Workspace allocation fails

Utf8Error(Utf8Error)

Create a new VclError from a UTF-8 error

Box(Box<dyn Error>)

Create a new VclError from a boxed error

Implementations

impl VclError

pub fn new(s: String) -> Self

Create a new Error from a string

pub fn as_str(&self) -> Cow<'_, str>

Trait Implementations

impl Debug for VclError

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

Formats the value using the given formatter.

impl Display for VclError

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

Formats the value using the given formatter.

impl Error for VclError

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<&'static CStr> for VclError

fn from(s: &'static CStr) -> Self

Converts to this type from the input type.

impl From<&'static str> for VclError

fn from(s: &'static str) -> Self

Converts to this type from the input type.

impl From<Box<dyn Error>> for VclError

fn from(source: Box<dyn Error>) -> Self

Converts to this type from the input type.

impl From<String> for VclError

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for VclError

fn from(source: Utf8Error) -> Self

Converts to this type from the input type.
