Enum CompileError 

pub enum CompileError {
    Parse(ParseError),
    Io(String),
    Build(String),
    Runtime(String),
    Ownership(LogosError),
}

Errors that can occur during the LOGOS compilation pipeline.

This enum represents the different stages where compilation can fail, from parsing through to runtime execution.

Error Hierarchy

CompileError
├── Parse      ← Lexing, parsing, or static analysis
├── Io         ← File system operations
├── Build      ← Rust compilation (cargo build)
├── Ownership  ← Translated borrow checker errors
└── Runtime    ← Program execution failure

Error Translation

The Ownership variant contains LOGOS-friendly error messages translated from rustc’s borrow checker errors (E0382, E0505, E0597) using the diagnostic module.

Variants

Parse(ParseError)

Parsing or static analysis failed.

This includes lexer errors, syntax errors, escape analysis failures, ownership analysis failures, and Z3 verification failures.

Io(String)

File system operation failed.

Typically occurs when reading source files or writing output.

Build(String)

Rust compilation failed (cargo build).

Contains the raw stderr output from rustc when diagnostic translation was not possible.

Runtime(String)

Runtime execution failed.

Contains stderr output from the executed program.

Ownership(LogosError)

Translated ownership/borrow checker error with LOGOS-friendly message.

This variant is used when rustc reports errors like E0382 (use after move) and we can translate them into natural language error messages that reference the original LOGOS source.

Trait Implementations

impl Debug for CompileError

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

Formats the value using the given formatter.

impl Display for CompileError

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

Formats the value using the given formatter.

impl Error for CompileError

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<CompileError> for BuildError

fn from(e: CompileError) -> Self

Converts to this type from the input type.
