Struct BodyWithConfig

pub struct BodyWithConfig<'a> { /* private fields */ }

Available on crate feature dep_ureq only.

Configuration of how to read the body.

Obtained via one of:

• Body::with_config()
• Body::into_with_config()

Implementations

impl<'a> BodyWithConfig<'a>

pub fn limit(self, value: u64) -> BodyWithConfig<'a>

Limit the response body.

Controls how many bytes we should read before throwing an error. This is used to ensure RAM isn’t exhausted by a server sending a very large response body.

The default limit is u64::MAX (unlimited).

pub fn lossy_utf8(self, value: bool) -> BodyWithConfig<'a>

Replace invalid utf-8 chars.

true means that broken utf-8 characters are replaced by a question mark ? (not utf-8 replacement char). This happens after charset conversion regardless of whether the charset feature is enabled or not.

The default is false.

pub fn reader(self) -> BodyReader<'a>

Creates a reader.

The reader is either shared or owned, depending on with_config or into_with_config.

Example of owned vs shared

// Creates an owned reader.
let reader = ureq::get("https://httpbin.org/get")
    .call()?
    .into_body()
    // takes ownership of Body
    .into_with_config()
    .limit(10)
    .reader();

// Creates a shared reader.
let reader = ureq::get("https://httpbin.org/get")
    .call()?
    .body_mut()
    // borrows Body
    .with_config()
    .limit(10)
    .reader();

pub fn read_to_string(self) -> Result<String, Error>

Read into string.

Caution: without a preceeding limit(), this becomes an unbounded sized String. A bad server could exhaust your memory.

Example

// Reads max 10k to a String.
let string = ureq::get("https://httpbin.org/get")
    .call()?
    .body_mut()
    .with_config()
    // Important. Limits body to 10k
    .limit(10_000)
    .read_to_string()?;

pub fn read_to_vec(self) -> Result<Vec<u8>, Error>

Read into vector.

Caution: without a preceeding limit(), this becomes an unbounded sized Vec. A bad server could exhaust your memory.

Example

// Reads max 10k to a Vec.
let myvec = ureq::get("https://httpbin.org/get")
    .call()?
    .body_mut()
    .with_config()
    // Important. Limits body to 10k
    .limit(10_000)
    .read_to_vec()?;
