Enum ParseMemSizeError 

#[non_exhaustive]
pub enum ParseMemSizeError {
    Empty,
    MissingDigits,
    InvalidCharacter,
    Overflow,
}

Failure to parse a MemSize from the grammar ^\d+(G|M|K)?$

#[non_exhaustive]: today’s four variants exhaust one frozen grammar, but a future revision of it — fractional sizes (1.5G), or a binary-vs-decimal unit distinction — would want its own variant rather than folding into Self::InvalidCharacter’s catch-all, and shep-core is a published library an out-of-tree matcher should not break for the day that lands (IR-20).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

The input string was empty

MissingDigits

A unit suffix with no digits before it ("M")

InvalidCharacter

A character outside ASCII digits plus one optional trailing G/M/K — covers lowercase units, whitespace, signs, fractions, and multi-letter suffixes such as "MB"

Overflow

The quantity in bytes does not fit in u64

impl Eq for ParseMemSizeError

impl Error for ParseMemSizeError

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
