Struct RuntimeConfigResolver

pub struct RuntimeConfigResolver { /* private fields */ }

Spin’s default resolution of runtime configuration for SQLite databases.

This type implements how Spin CLI’s SQLite implementation is configured through the runtime config toml as well as the behavior of the “default” label.

Implementations

impl RuntimeConfigResolver

pub fn new( default_database_dir: Option<PathBuf>, local_database_dir: PathBuf, ) -> Self

Create a new SpinSqliteRuntimeConfig

This takes as arguments:

• the directory to use as the default location for SQLite databases. Usually this will be the path to the .spin state directory. If None, the default database will be in-memory.
• the path to the directory from which relative paths to local SQLite databases are resolved. (this should most likely be the path to the runtime-config file or the current working dir).

pub fn resolve(&self, table: &impl GetTomlValue) -> Result<RuntimeConfig>

Get the runtime configuration for SQLite databases from a TOML table.

Expects table to be in the format:

[sqlite_database.$database-label]
type = "$database-type"
... extra type specific configuration ...
```

Configuration is automatically added for the 'default' label if it is not provided.

pub fn get_connection_creator( &self, config: TomlRuntimeConfig, ) -> Result<Arc<dyn ConnectionCreator>>

Get a connection creator for a given runtime configuration.

impl RuntimeConfigResolver

pub fn default(&self) -> Arc<dyn ConnectionCreator>

The [ConnectionCreator] for the ‘default’ label.
