        path: String,
        source: Error,

}

Unified error type for plotlars I/O and plot construction failures.

This enum is #[non_exhaustive] – new variants may be added in minor releases without breaking downstream match arms that include a wildcard.

Example

use plotlars_core::io::{CsvReader, PlotlarsError};

fn main() -> Result<(), PlotlarsError> {
    let df = CsvReader::new("data/penguins.csv").finish()?;
    Ok(())
}

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.

Io

File not found, permission denied, or other I/O error.

Fields

path: String

source: Error

CsvParse

CSV parsing failure.

Fields

path: String

source: Box<dyn Error + Send + Sync>

ParquetParse

Parquet parsing failure.

Fields

path: String

source: Box<dyn Error + Send + Sync>

ColumnNotFound

A required column was not found in the DataFrame.

Fields

column: String

available: Vec<String>

TypeMismatch

A column’s data type did not match what the plot expected.

Fields

column: String

expected: String

actual: String

PlotBuild

Plot construction failure.

Fields

message: String

Trait Implementations

impl Debug for PlotlarsError

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

Formats the value using the given formatter.

impl Display for PlotlarsError

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

Formats the value using the given formatter.

impl Error for PlotlarsError

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>)
