🔬 This is a nightly-only experimental API. (int_error_matching #22639)

it can be useful to match errors when making error messages for integer parsing

[−] Expand description

Enum to store the various types of errors that can cause parsing an integer to fail.

Variants (Non-exhaustive)

[+] This enum is marked as 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

🔬 This is a nightly-only experimental API. (int_error_matching #22639)

it can be useful to match errors when making error messages for integer parsing

[−] Expand description

Value being parsed is empty.

Among other causes, this variant will be constructed when parsing an empty string.

InvalidDigit

🔬 This is a nightly-only experimental API. (int_error_matching #22639)

it can be useful to match errors when making error messages for integer parsing

[−] Expand description

Contains an invalid digit.

Among other causes, this variant will be constructed when parsing a string that contains a letter.

Overflow

🔬 This is a nightly-only experimental API. (int_error_matching #22639)

it can be useful to match errors when making error messages for integer parsing

[−] Expand description

Integer is too large to store in target integer type.

Underflow

🔬 This is a nightly-only experimental API. (int_error_matching #22639)

it can be useful to match errors when making error messages for integer parsing

[−] Expand description

Integer is too small to store in target integer type.

Zero

🔬 This is a nightly-only experimental API. (int_error_matching #22639)

it can be useful to match errors when making error messages for integer parsing

[−] Expand description

Value was Zero

This variant will be emitted when the parsing string has a value of zero, which would be illegal for non-zero types.
