Enum pel::Error

pub enum Error {
    CompileShader(String),
    LinkProgram(String),
    OutOfBounds {
        upper_bound: (usize, usize),
        indices: (usize, usize),
    },
}

Errors that can be created by this library.

Variants

CompileShader(String)

Shader compilation error.

String contains error message returned by OpenGL shader compiler.

LinkProgram(String)

Program linking error.

String contains error message returned by OpenGL shader program linker.

OutOfBounds

Out of bounds error.

This error is formed when x ∉ [0; width), y ∉ [0; height).

Fields of OutOfBounds

upper_bound: (usize, usize)

(width, height) of indexable area. Lower bound is implied to be (0, 0).

indices: (usize, usize)

(x, y) that are out of bounds.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 1.41.0:

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
