Implementations

impl Values

pub fn new() -> Self

Create empty values

pub fn from_file<P: AsRef<Path>>(path: P) -> Result<Self>

Load values from a YAML file

pub fn from_yaml(yaml: &str) -> Result<Self>

Parse values from YAML string

pub fn from_json(json: &str) -> Result<Self>

Parse values from JSON string

pub fn merge(&mut self, overlay: &Values)

Deep merge another Values into this one

Rules:

• Scalars: overlay replaces base
• Objects: recursive merge
• Arrays: overlay replaces base (not appended)

pub fn merge_all(values: Vec<Values>) -> Self

Merge multiple values in order

pub fn set(&mut self, path: &str, value: JsonValue) -> Result<()>

Set a value by dotted path (e.g., “image.tag”)

pub fn get(&self, path: &str) -> Option<&JsonValue>

Get a value by dotted path

pub fn inner(&self) -> &JsonValue

Get the inner JSON value

pub fn into_inner(self) -> JsonValue

Convert to JSON value

pub fn is_empty(&self) -> bool

Check if values are empty

pub fn with_schema_defaults(schema_defaults: Values, base: Values) -> Self

Merge with schema defaults applied first

The merge order is: schema defaults (lowest priority) -> base values (higher priority) This ensures that schema defaults are only used when values are not explicitly set.

pub fn scope_for_subchart(&self, subchart_name: &str) -> Values

Scope values for a subchart

When rendering a subchart, it should only see:

1. Values under <subchart_name>.* in the parent, as its root values
2. Global values under global.* preserved as-is

The subchart’s own values.yaml defaults are merged separately before this.

Example

Parent values:

global:
  imageRegistry: docker.io
redis:
  enabled: true
  replicas: 3
postgresql:
  enabled: false

Calling scope_for_subchart("redis") produces:

global:
  imageRegistry: docker.io
enabled: true
replicas: 3

pub fn for_subchart( subchart_defaults: Values, parent_values: &Values, subchart_name: &str, ) -> Values

Merge subchart defaults with scoped parent values

This is the complete subchart value resolution:

1. Start with subchart’s own values.yaml defaults
2. Merge in the scoped values from parent

Arguments

• subchart_defaults - Values from the subchart’s values.yaml
• parent_values - Parent’s merged values
• subchart_name - Name of the subchart (for scoping)

pub fn export_to_parent(&self, subchart_name: &str) -> Values

Export subchart values back to parent namespace

This is the inverse of scope_for_subchart - takes subchart-scoped values and wraps them under the subchart’s namespace for parent access.

Example

Subchart values:

global:
  imageRegistry: docker.io
enabled: true
replicas: 3

Calling export_to_parent("redis") produces:

global:
  imageRegistry: docker.io
redis:
  enabled: true
  replicas: 3

pub fn scope_json_for_subchart( parent_json: &JsonValue, subchart_name: &str, ) -> Values

Scope values for a subchart from raw JsonValue

Same as scope_for_subchart but works with &JsonValue directly, useful when values are already in JsonValue form (e.g., from TemplateContext).

pub fn for_subchart_json( subchart_defaults: Values, parent_json: &JsonValue, subchart_name: &str, ) -> Values

Merge subchart defaults with scoped parent values from JsonValue

Same as for_subchart but accepts &JsonValue for parent values.
