Implementations

impl Utm

pub fn new() -> Self

Construct a Utm with all fields None.

Use the with_* builder methods to populate individual UTM parameters. Only non-None fields are serialised into the JSON.

Returns

An empty Utm instance.

Example

use cow_app_data::Utm;

let utm = Utm::new().with_source("twitter").with_campaign("launch-2025");
assert!(utm.has_source());
assert!(utm.has_campaign());
assert!(!utm.has_medium());

pub fn with_source(self, source: impl Into<String>) -> Self

Set the utm_source parameter (e.g. "twitter", "google").

Parameters

• source — the traffic source identifier.

Returns

self with utm_source set.

pub fn with_medium(self, medium: impl Into<String>) -> Self

Set the utm_medium parameter (e.g. "cpc", "email").

Parameters

• medium — the marketing medium identifier.

Returns

self with utm_medium set.

pub fn with_campaign(self, campaign: impl Into<String>) -> Self

Set the utm_campaign parameter (e.g. "launch-2025").

Parameters

• campaign — the campaign name.

Returns

self with utm_campaign set.

pub fn with_content(self, content: impl Into<String>) -> Self

Set the utm_content parameter for A/B testing or ad variants.

Parameters

• content — the content variant identifier.

Returns

self with utm_content set.

pub fn with_term(self, term: impl Into<String>) -> Self

Set the utm_term parameter for paid search keywords.

Parameters

• term — the search keyword or term.

Returns

self with utm_term set.

pub const fn has_source(&self) -> bool

Returns true if the utm_source parameter is set.

pub const fn has_medium(&self) -> bool

Returns true if the utm_medium parameter is set.

pub const fn has_campaign(&self) -> bool

Returns true if the utm_campaign parameter is set.

pub const fn has_content(&self) -> bool

Returns true if the utm_content parameter is set.

pub const fn has_term(&self) -> bool

Returns true if the utm_term parameter is set.
