pub enum LinkError {
    NotFound(String),
    UndefinedLibrary(String),
}

An error linking a library to bytecode.

Variants

NotFound(String)

Error when attempting to link a library when its placeholder cannot be found.

UndefinedLibrary(String)

impl Error for LinkError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<LinkError> for DeployError

fn from(source: LinkError) -> Self

Performs the conversion.
