Result extension methods for adapting third party errors to Error.

Required Methods

fn lossy_chain<S: Into<KString>>(self, msg: S) -> Result<T>

Create an Error ignoring E as the cause.

Example

use std::io;
use liquid_core::error::Result;
use liquid_core::error::ResultLiquidReplaceExt;

let error = Err(io::Error::new(io::ErrorKind::NotFound, "Oops"));
let error: Result<i32> = error.lossy_chain("Missing liquid partial");

fn lossy_chain_with<F>(self, msg: F) -> Result<T>where F: FnOnce() -> KString,

Create an Error ignoring E as the cause.

Example

use std::io;
use liquid_core::error::Result;
use liquid_core::error::ResultLiquidReplaceExt;

let filename = "foo";
let error = Err(io::Error::new(io::ErrorKind::NotFound, "Oops"));
let error: Result<i32> = error
    .lossy_chain_with(|| format!("Missing liquid partial: {}", filename).into());

fn replace<S: Into<KString>>(self, msg: S) -> Result<T>

Create an Error ignoring E as the cause.

Example

use std::io;
use liquid_core::error::Result;
use liquid_core::error::ResultLiquidReplaceExt;

let error = Err(io::Error::new(io::ErrorKind::NotFound, "Oops"));
let error: Result<i32> = error.replace("Missing liquid partial");

fn replace_with<F>(self, msg: F) -> Result<T>where F: FnOnce() -> KString,

Create an Error ignoring E as the cause.

Example

use std::io;
use liquid_core::error::Result;
use liquid_core::error::ResultLiquidReplaceExt;

let filename = "foo";
let error = Err(io::Error::new(io::ErrorKind::NotFound, "Oops"));
let error: Result<i32> = error
    .replace_with(|| format!("Missing liquid partial: {}", filename).into());
