Struct Emulation

Source

pub struct Emulation { /* private fields */ }

Available on crate feature emulation only.

Expand description

Represents the configuration options for emulating a client profile and platform.

The Emulation struct allows you to configure various aspects of profile and platform emulation, including the profile, platform, and whether to enable certain features like HTTP/2 or headers.

Implementations§

Source §

Create a builder for building Emulation. On the builder, call .profile(...)(optional), .platform(...)(optional), .http2(...)(optional), .headers(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of Emulation.

Source §

impl Emulation

Source

pub fn random() -> Emulation

Returns a random variant of the Profile enum.

§Examples

use wreq_util::Emulation;

let random_emulation = Emulation::random();
println!("{:?}", random_emulation);

Source

pub fn weighted_random() -> Emulation

Returns a market-share weighted random Emulation.

Unlike Emulation::random, selection is biased toward popular browser families and their most recent versions, and each profile is only paired with platforms it ships on.

Browser family and version weights are derived from StatCounter Global Stats data retrieved in June 2026:

Browser market share: https://gs.statcounter.com/browser-market-share#monthly-202506-202606

Browser version market share: https://gs.statcounter.com/browser-version-market-share#monthly-202506-202606

StatCounter requests attribution for use of its data. See: https://creativecommons.org/licenses/by-sa/3.0/

§Examples

use wreq_util::Emulation;

let random_emulation = Emulation::weighted_random();
println!("{:?}", random_emulation);
