Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidUtcWithNamedTz {
        tz: String,
    },
    InvalidIanaName(String),
    InvalidFormat(String),
    Io(Error),
}

Errors raised by the rusty-ts library API.

Marked #[non_exhaustive] to allow new variants in minor releases.

Example

use rusty_ts::{Error, TimestamperBuilder};

// Pattern-match on specific variants for actionable handling.
let result = TimestamperBuilder::new()
    .utc(true)
    .tz_name("Asia/Tokyo")
    .build();

match result {
    Err(Error::InvalidUtcWithNamedTz { tz }) => {
        eprintln!("cannot combine -u with --tz={tz}");
    }
    Err(Error::InvalidIanaName(name)) => {
        eprintln!("unknown IANA timezone: {name}");
    }
    Err(other) => eprintln!("error: {other}"),
    Ok(_) => unreachable!("we configured a conflict"),
}

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.

InvalidUtcWithNamedTz

-u (UTC) and --tz=<name> were both specified, which is invalid. Mirrors the CLI-layer FR-020 mutual-exclusion check at the library layer so library consumers do not depend on the CLI to catch it.

Fields

tz: String

The IANA name the caller supplied.

InvalidIanaName(String)

The named IANA timezone could not be resolved (e.g., typo, removed zone). Carries the offending input.

InvalidFormat(String)

The strftime format string is malformed or unsupported. Carries the offending format string.

Io(Error)

Underlying IO error, surfaced from BufRead/Write operations.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
