Struct ConfigChange 

#[non_exhaustive]
pub struct ConfigChange {
    pub element: String,
    pub old_value: String,
    pub new_value: String,
    pub change_type: ChangeType,
    pub advices: Vec<Advice>,
    /* private fields */
}

Output generated from semantically comparing two versions of a service configuration.

Includes detailed information about a field that have changed with applicable advice about potential consequences for the change, such as backwards-incompatibility.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

element: String

Object hierarchy path to the change, with levels separated by a ‘.’ character. For repeated fields, an applicable unique identifier field is used for the index (usually selector, name, or id). For maps, the term ‘key’ is used. If the field has no unique identifier, the numeric index is used. Examples:

• visibility.rules[selector==“google.LibraryService.ListBooks”].restriction
• quota.metric_rules[selector==“google”].metric_costs[key==“reads”].value
• logging.producer_destinations[0]

old_value: String

Value of the changed object in the old Service configuration, in JSON format. This field will not be populated if ChangeType == ADDED.

new_value: String

Value of the changed object in the new Service configuration, in JSON format. This field will not be populated if ChangeType == REMOVED.

change_type: ChangeType

The type for this change, either ADDED, REMOVED, or MODIFIED.

advices: Vec<Advice>

Collection of advice provided for this change, useful for determining the possible impact of this change.

Implementations

impl ConfigChange

pub fn new() -> Self

pub fn set_element<T: Into<String>>(self, v: T) -> Self

Sets the value of element.

pub fn set_old_value<T: Into<String>>(self, v: T) -> Self

Sets the value of old_value.

pub fn set_new_value<T: Into<String>>(self, v: T) -> Self

Sets the value of new_value.

pub fn set_change_type<T: Into<ChangeType>>(self, v: T) -> Self

Sets the value of change_type.

pub fn set_advices<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<Advice>,

Sets the value of advices.

Trait Implementations

impl Clone for ConfigChange

fn clone(&self) -> ConfigChange

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConfigChange

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

Formats the value using the given formatter.

impl Default for ConfigChange

fn default() -> ConfigChange

Returns the “default value” for a type.

impl Message for ConfigChange

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ConfigChange

fn eq(&self, other: &ConfigChange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
