Enum CacheError 

pub enum CacheError {
    ParseError(String),
    InvalidStringOffset(usize),
    InvalidMagic,
    TruncatedFile,
    InvalidEndianness,
}

Errors that can occur during cache parsing and processing.

This enum covers all possible failure modes when parsing ld.so.cache files, from file format issues to data corruption.

Variants

• ParseError - Generic parsing failure with descriptive message
• InvalidStringOffset - String offset points outside the string table
• InvalidMagic - File doesn’t start with a recognized magic number
• TruncatedFile - File is too short to contain valid cache data
• InvalidEndianness - Unsupported byte order in cache file

Example

let invalid_data = b"not a cache file";
let result = parse_ld_cache(invalid_data);
 
match result {
    Err(CacheError::InvalidMagic) => {
        println!("File is not a valid ld.so.cache");
    }
    Err(CacheError::TruncatedFile) => {
        println!("Cache file is incomplete");
    }
    Err(e) => println!("Other error: {}", e),
    Ok(_) => println!("Successfully parsed"),
}

Variants

ParseError(String)

Generic parsing error with descriptive message

InvalidStringOffset(usize)

String offset points beyond the string table bounds

InvalidMagic

File doesn’t begin with a recognized magic number

TruncatedFile

File is too short to contain required cache structures

InvalidEndianness

Cache uses unsupported byte order

Trait Implementations

impl Clone for CacheError

fn clone(&self) -> CacheError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheError

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

Formats the value using the given formatter.

impl Display for CacheError

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

Formats the value using the given formatter.

impl Error for CacheError

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 PartialEq for CacheError

fn eq(&self, other: &CacheError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
